Description

IOA0 ~ IOA3 I/O IOA0 ~ IOA3 as bi-direction I/O port

IOB0/INT

I/O Bi-direction I/O pin with system wake-up function / External interrupt input

IOB1 ~ IOB7 I/O Bi-direction I/O port with system wake-up function

T0CKI

I Clock input to Timer0. Must be tied to Vss or Vdd, if not in use, to reduce current

consumption

RSTB

I System clear (RESET) input. This pin is an active low RESET to the device.

OSCI

X’tal type: Oscillator crystal input

I RC type: Clock input of RC oscillator

OSCO

O

X’tal type: Oscillator crystal output.

RC mode: Outputs with the instruction cycle rate

Vdd

- Positive supply

Vss

- Ground

Legend: I=input, O=output, I/O=input/output
