P1.0 (T2)

P1.1 (T2EX)

P1.2

Port0 is an open-drain, bi-directional IO

port. When 1s are written to Port0, they

become high-impedance inputs. Port0 is

also multiplexed with low-order address

or data bus during accesses to external

program and data memory.

BU General-purposed I/O with weak pull-up

resistance inside. When 1s are written

into Port1, the strong output driving

PMOS only turn-on two clock periods

and then the weak pull-up resistance

keep the port high.

P1.3

P1.4

P1.5

P1.0 is also used as one of event

sources for timer2, or output carrier of

timer2, alias T2.

P1.6

P1.7

P1.1 is also used as one of

interrupt-controlling sources for time2,

alias T2EX.

P2.0 (A8)

BU Port2 is an 8-bit bi-directional I/O port

with pull-up resistance. Except being as

GPIO, Port2 emits the high-order

address byte during accessing to

external program and data memory.

BU General-purposed I/O with weak pull-up

resistance inside. When 1s are written

PMOS only turn-on two clock periods

and then the weak pull-up resistance
