5.3 Operations and Functions
5.3.1 Internal States
Internal states are the following three states, © Speech state---- Voice waveform is output from the DAO pin. © Waiting state ----- Non-speech state in which the oscillation is continued while the circuit being reset to the initial status. ‘The DAO pin is fixed at VDD/2. © Stand-by state-- Non-speech state in which the oscillation is stopped while resetting the circuit to the initial status, The DAO pin is fixed to the GND level. Each state above can be monitored at the EOS (End of Speech) output and the APD (Audio Power Down) output. For the timings of EOS, APD pin signals, see 6.4. AC characteristics. ‘The three states and outputs of the TC8801 are shown in the following table.

Note that, in the automatic power stand-by function(APS =), the function of the ACL and STBY become different from those in this case. For more details, see 5.9.2.

5.4 Setting of Phrase ==
Set a speech phrase using the SELO — SEL5. However, TC8801 does not synthesize with all pins — SELO — SELS set low. Therefore, a total number of selectable phrases with SELO — SELS is 63. Each = phrase number corresponds to the setting of the pins SELO — SELS as shown in the following Table = 52. = Table 5.2 Phrase no. vs. the SELO ~ SELS pin poo oe fo Po Po fo 5.5 ‘Speech Start Input ‘The method for operating the TC8801 is classified into the CPU control using microprocessor ete. and the manual control using switches, TC8801 is in CPU control mode with the CPUM high, and in the manual control mode with CPUM low. And there are two kinds of speech start inputs for each control mode. Once a speech start input is given, voice waveform is output from the DAO, while the EOS changes from high to low.

In the manual control, the START and SELO - SEL are connected to the chattering preventing circuit, Therefore, after passing the chattering preventing time, the phrase number is read and the speech begins, (Fig. 5.3) This method of speech beginning input is inhibited with the random function.

5.6 End of Speech
During speech, the EOS pin outputs low level, and changes to high level upon completion of speech. Speech is forcefully terminated during speech by any of the following three methods. ‘The EOS becomes high even after forced terminating of speech. qa) The case of using the ACL The ACL pin is provided for initializing. Speech is forcefully terminated by setting the ACL low. (See 6.4, AC characteristics ) After termination of speech, the TC8801 becomes waiting or stand-by state according to low or high level at the APS pin, respectively. (2) The case of using the STBY Speech is forcefully terminated by setting the STBY high when the APS is set low After termination, the TC8801 becomes stand-by state. (3) ‘The case of changing speech phrase In this case, a phrase without voice data (the terminating phrase ; the phrase of which the start and the end addresses are the same in L/I ROM) is first set up upon development of the mask ROM. ‘Then a speech is terminated when assigning this phrase during the speech and giving the speech start input during the speech, (For the case of changing a phrase during speech, see next section 5.7)

It prevents error operation due to chattering by switches connected to the START and the SELO - SELS. Speech is begun provided high level is maintained stably at about 32 ms after chattering. Before the switch is once turned off and then again on, apply low level stably for 32 ms or more. ‘Switch input QM | teh ton | teh | toff Chattering time _ (32 ms or less) [ton _| Switch ONtime (32 ms or above) Switch OFF time (32 ms or above) feux = 640kHz (ceramic oscillation) 64kHz (RC oscillation) Fig.5.9 Chattering

59 Stand-by Function
‘The TC8801 is provided with the stand-by function to decrease current consumption. ‘Transition to the stand-by state is activated by using the STBY or the APS. In addition, the APD pin is also useful when turning on / off the power supply to an external cireuit (audio cireuit such as Amplifier and Filter). ‘The stand-by state can be assigned in any of the CPU or manual control. —

In the stand- by state using the STBY, synthesis is not begun by any speech start input, 2, Stand-by state by APS (automatic power stand-by state) By fixing the APS to high, the internal circuit is automatically placed in the stand-by state when speech is finished. Speech is forcefully terminated by setting the ACL low during speech, resulting is stand-by state. ‘The STBY pin must be fixed high or open in this case to prevent current of pull up resistors of STBY pin, The automatic power stand-by function is disabled provided the START is high and at least one of the SELO — SELS is high.

Stand-by state of the external circuit using APD Output pin When TC8801 goes to the stand-by state, the APD (output) goes from low to high. Therefore, by using this pin signal, the stand-by (power down) for the external circuit is automatically effected during non-speech period. Fig.5.10 show the relationships between stand-by state by the STBY input and the APD output when the APS pin is low, and those when the APS is high. (For more details, see the AC characteristics. ) Referring to Fig.6.10, time when the output level of the DAO changes is not the same as that of the APD pin. Now assume the power supply to the external circuit is turned off with the APD output high. Then, the power supply connected to external audio circuit is in off state when the level of the DAO Voice Output pin changes between 1/2 Vpp and GND (at tstep in the figure). Therefore, noise due to the change of output level at the DAO is reduced,

5.10.1 Repeat Function
In manual control, an assigned phrase is repeatedly synthesized by setting the REPEAT high and giving speech start input -1 or -2. In the CPU control, speech is begun by speech start input -1 only. (Speech start input -2 is inhibited. ) Repeat speech is terminated by the STBY (STBY = high ), the ACL(ACL = low ), or resetting of the repeat function (REPEAT = low ). With the STBY or ACL used for termination, the speech is terminated when it is effected. On the other hand, with the repeat function resetting used for resetting, the phrase in speech upon resetting is synthesized to the end of the phrase then terminated.
