GENERAL DESCRIPTION
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.
The Z86317 device provides two on-chip 8-bit program-
mable counter/timers with a large number of user-select-
able modes. 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).

Notes:
The device is functional to VLV voltage. The minimum operational VDD is
determined by the value of the VLV voltage at ambient temperature. The
VLV voltage increases as the temperature decreases.
