Each counter/timer is driven by its own 6-bit programmable prescaler. The Z86317 counter/timers offload system real-time tasks such as counting/timing and input/output data communications for increased sys- tem efficiency. Notes: All Signals with a preceding front slash, "/", are active Low, e.g.; B//W (WORD is active Low); /B/W (BYTE is active Low, only). Power connections follow conventional descriptions below: Connection Circuit Device Power V CC VDD Ground GND V SS The Z86317 is a member of the Z8 ® family of CMOS microcontrollers architected to be used in mouse applica- tions. These devices offer on-board pull-up and pull-down resistors, a scalable trip-point buffer to accommodate opto-transistor outputs, and high drive ports capable of up to 10 mA current sinking per pin (six pins maximum). A permanently enabled Watch-Dog Timer ensures opera- tional reliability across a broad range of mouse application environments. The precision RC oscillator filters out high- frequency noise from the oscillator input pin. When config- ured as inputs, P24-P27 are configured as voltage divider (25K pull-up / 7.5K pull-down). The input levels are ad- justed for connection to the emitters of the opto-transistors and switch at a voltage level of 0.4 V DD. For applications requiring powerful I/O capabilities, the Z86317 provides dedicated input and output lines that are grouped into three ports. There are two basic address spaces available to support this configuration: Program Memory, and 124 bytes of general-purpose registers. *General Purpose n 4.5- to 5.5-Volt Operating Range n 0°C to + 40°C Operating Temperature Range n Low-Power Consumption: 33 mW (Typical)
