5.17.3 Port Mode 2 Register (PM2)
The port mode 2 register is organized as 4-bit binary register (PM2.0 to PM2.3). PM2 can be used to
control the input/output mode of port RB. PM2 is controlled by the MOV PM2, #I instruction. The bit
description is as follows:
PM2
Note: W means write only.

Bit 0 = 0 RB.0 works as output pin; Bit 0 = 1 RB.0 works as input pin
Bit 1 = 0 RB.1 works as output pin; Bit 1 = 1 RB.1 works as input pin
Bit 2 = 0 RB.2 works as output pin; Bit 2 = 1 RB.2 works as input pin
Bit 3 = 0 RB.3 works as output pin; Bit 3 = 1 RB.3 works as input pin
At initial reset, the port RB is input mode (PM2 = 1111B).
5.17.4 Port Mode 6 Register (PM6)
The port mode 6 register is organized as 4-bit binary register (PM6.0 to PM6.3). PM6 can be used to
control the input/output mode of port P0. PM6 is controlled by the MOV PM6, #I instruction. The bit
description is as follows:

Bit 1 = 0 P0.1 works as output pin; Bit 1 = 1 P0.1 works as input pin
Bit 2 = 0 P0.2 works as output pin; Bit 2 = 1 P0.2 works as input pin
Bit 3 = 0 P0.3 works as output pin; Bit 3 = 1 P0.3 works as input pin
At initial reset, the port P0 is input mode (PM6 = 1111B).
5.18 Serial I/O interface
The bit 0 and bit 1 of port P0 can be used as a serial input/output port. P0.0 is the serial clock I/O pin
and P0.1 is the serial data I/O pin. A 4-bit binary register, Serial Interface Control register(SIC), controls
the serial port. SIC is controlled by the MOV SIC,#I instruction. The bit definition is as follow:
