Ground

PA0~PA1

PA4~PA5

I/O

Input and output ports.

In input mode, all PA pins could be set an internal pull-up resistor

(R=100Kohm). In output mode, it could be optioned as CMOS or

NMOS output independently. Also, PA0~PA3 could be optioned as 4

channels of 10-bit A/D converter input pins.

PB0~PB1

PB2 / PB4

I/O

Input and output ports. In input mode, it could have optioned internal

pull-up resistor with 100Kohm.

Also, it can be set as HALT and

STOP mode released source when the input signal is changed from

high to low. In output mode, it could be optioned as CMOS or NMOS

output independently.
