A8–A12
Bit-programmable I/O port for Schmitt trigger
input or open-drain output. Port0 can also be
configured as external interface address lines
A8–A12.
Bit-programmable I/O port for Schmitt trigger
input, push-pull, or open-drain output. Port1 can
alternatively be used as external interface
address/data lines AD0–AD7.
Bit-programmable I/O port for Schmitt trigger
input or push-pull output. Port2 can be
individually configured as external interrupt
inputs. Especially, P2.0–2.3 can be configured
for external bus control signal.
Same general characteristics as Port1. Port3 are
designed for to drive LED directly. P3.3 can be
used to system clock output (CLO) port.
Bit-programmable I/O port. Input mode or n-
channel open-drain output mode is software
assignable. Port4 can be individually configured
as external interrupt inputs. Pull-up resistors are
also software assignable. Especially, P4.1 can be
used T0CLK input and P4.3 also T0OUT for
Timer 0.
System clock input and output pin (for RC
oscillator, crystal/ceramic oscillator, or external
clock source)
External interrupt for bit-programmable port2 and
port4 pins when set to input mode.
RESET
signal input pin. Schmitt trigger input with
internal pull-up resistor.
External Memory Access (EA) pin with 2 modes:
0V = Normal Operation Mode
5V = ROMLESS Operation Mode
(Must be connected to V
SS
during normal
operation mode)
