Oscillator connection. Leave open when
external clock is input to CLK1. Maximum of
one external load.
Reset pin (active LOW). Note. The allowable
external capacitance connected to the RESET
pin is 100–1000 pF.
Service pin (active LOW). Alternates between
input and output at a 76-Hz rate.
Large current-sink capacity (20mA). General
I/O port. The output of timer/ counter 1 may be
routed to IO0. The output of timer/counter 2
may be routed to IO1.
General I/O port. The input to timer/counter 1
may be derived from one of IO4–IO7. The input
to timer/counter 2 may be derived from IO4.
General I/O port. May be used for serial
communication under firmware control.
Slave Select. Muxed with IO7.
