—
Oscillator connection or external clock
input.
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 (20 mA).
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.
Bidirectional memory data bus.
Read/write control output for external
memory.
Enable clock control output for external
memory.
Memory address output port.
Power input (5V nom). All V
be connected together externally.
Power input (0V, GND). All V
be connected together externally.
In-circuit test mode control. If Vpp is high
when RESET is asserted, the I/O, address
and data buses become Hi-Z.
Bidirectional port supporting communi-
cations in three modes.
No connect. Must not be connected on the
user’s PC board, since they may be
connected internal to the chip.
