DESCRIPTION
1 bit of Port 2: 4-bit quasi-bidirectional I/O port
bidirectional data line of the I2C-bus interface; or 1 bit of Port 2: 4-bit
quasi-bidirectional I/O line
bidirectional clock line of the I2C-bus interface
8 bits of Port 0: 8-bit quasi-bidirectional I/O port
Interrupt/Test 0: external interrupt input (negative edge triggered)/test input
pin. When used as a test input, this pin is directly tested by conditional branch
instructions JT0 and JNT0.
Test 1: test input pin, directly tested by conditional branch instructions JT1 and
JNT1. T1 may also be selected as an input to the 8-bit timer/event counter via
the STRT CNT instruction.
ground: circuit earth potential
oscillator input: input from a crystal which determines the internal oscillator
frequency or an external clock generator
oscillator output: output of the inverting amplifier
reset input: used to initialize the microcontroller (active HIGH); also output of
power-on-reset circuit
8 bits of Port 1: 8-bit quasi-bidirectional I/O port
2 bits of Port 2: 4-bit quasi-bidirectional I/O port
power supply: 2.5 V to 5.5 V
