Description

3-bit I/O port.

1-bit and 4-bit read/write and test is possible.

Port 0 is software configurable as input or output. 3-bit

pull-up resistors are software assignable.

4-bit I/O port.

1-bit and 4-bit read/write and test is possible.

Individual pins are software configurable as input or

output. 4-bit pull-up resistors are software assignable.

Same as port 2.

Ports 2 and 3 can be addressed by 1, 4, and 8-bit

read/write and test instruction.

4/2-bit I/O ports. N-channel open-drain or push-pull

output. 1, 4, and 8-bit read/write and test is possible.

Ports 4 and 5 can be paired to support 8-bit data

transfer. Pull-up resistors are assignable to port unit by

software control.

P6.0-P6.3

I/O 4-bit I/O ports. Port 6 pins are individually software

configurable as input or output. 1-bit and 4-bit read/write

and test is possible. 4-bit pull-up resistors are software

assignable.

BTCO

I/O Basic timer clock output

CLO

I/O CPU clock output

BUZ

I/O 2, 4, 8 or 16 kHz frequency output for buzzer sound with

4.19MHz main-system clock or 32.768 kHz sub-system

clock.

XOUT, XIN

– Crystal, ceramic, or RC oscillator signal for main-

system clock. (For external clock input, use XIN and

input XIN’s reverse phase to XOUT)

XTOUT,

XTIN

– Crystal oscillator signal for sub-system clock.

(For external clock input, use XTIN and input XTIN’s

reverse phase to XTOUT)

INT0, INT1 I/O External interrupts. The triggering edge for INT0 and

Int1 is selectable. Only INT0 is synchronized with the

system clock.
