Revision A2
Port Mode Register 1 and 2 (PM1, PM2 with SR=36H, 37H)
The port mode 1, 2 registers are organized as a 4-bit binary PM1.0 to PM1.3 and PM2.0~PM2.3. PM1 (PM2) can be used
to control the input/output mode of port RA (RB) . PM1 (PM2) is controlled by the MOV PM1, #I (MOV PM2, #I)
instruction. The bit descriptions are as follows:
PM1

1
0
RA1IN
RA3IN
RA0IN
RA2IN
RA0IN = 0 RB0 works as output pin;
= 1 RB.0 works as input pin
RA1IN = 0 RB1 works as output pin;
= 1 RB.1 works as input pin
RA2IN = 0 RB2 works as output pin;
=1 RB.2 works as input pin
RA3IN = 0 RB3 works as output pin;
= 1 RB.3 works as input pin
PM2

RB0IN
RB2IN
RB0IN = 0 RB0 works as output pin;
= 1 RB.0 works as input pin
RB1IN = 0 RB1 works as output pin;
= 1 RB.1 works as input pin
RB2IN = 0 RB2 works as output pin;
=1 RB.2 works as input pin
RB3IN = 0 RB3 works as output pin;
= 1 RB.3 works as input pin
All bit can be read/write and set/clear by user.
At initial reset, port RA, RB is input mode (PM1, PM2 = 1111B).
Port A Register (PORTA with SR=38H)
This register stores the current port RA pin state by MOV PORTA, R and MOV R, PORTA instructions. When port A is
input, the register is read only. Otherwise PORTA is written during port RA output mode.

PA3
PA1

Port B Register (PORTB with SR=39H)
This register stores the current port RB pin state by MOV PORTB, R and MOV R, PORTB instructions. When port RB is
input, the register is read only. Otherwise PORTB is writen during port RB output mode.
