26 XLDEN INU D LD enable input pin. In a high-level or open mode, LD becomes off and open. This state is suited to check the LD characteristics in keeping a connection to the IC. At the time power off, both ends of LD are short-circuited by the IC for protection. In the low-level, it returns to a normal operation. 27 XCLR IND D Clear signal input pin. Sets an LDDENB register to "0" in the low-level and presets the status of each DAC and each switch to an initial state as defined separately. But six registers for an abnormal detection are not cleared. In this state, each output of a current amplification 1, 2, 3 are in the off state and a shunt circuit becomes on to continue to protect LD. Setting this pin to the high-level and the LDDENB register to "1", it returns to a normal operation. 28 DGND PS D GND pin exclusive for a logic circuit. Must be used in the same potential as other GND pins. 29 XLDERR OUT D Laser abnormality detection output pin. When a supply voltage or a laser light emission exceeds a fixed range, it goes to low-level. A supply voltage abnormality is detected for the volt- age drop (3.9 V or less) or voltage rise (6.1 V or more). And an abnormal light emission is detected for an excessive or weaker light emission set up by 4-bit DAC5 and DAC6. This abnormality detection is latched so as to prevent it from being reset until ERRCLR register is set to "1". Further, each DAC output of a playback current, a peak current and a bias current can be set to off, a shunt circuit be set to on and LD between anode and GND be short-circuited by 100 W so that LD can be protected. This protection function is latched to keep it from being reset until ERRCLR is set to "1". Selection of either operation or non-operation for this opera- tion can be made by an STPMSK register.

comes out at switching a detection level of excessive or insufficient light emission by RPHOLD. Set a mask time by an external capacitor between PWMSK and DGND and the resistor (10 kW ) inside the IC. This pin is for a schmitt-trigger input.

Timing chart" for the timing chart. 6) Each signal line is pulled up and down as below: Pull-down to GND with 100 kW AD0 to AD3 DT0 to DT7 Pull-up to V CC with 100 kW XWR WRD
