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).
Port Mode 3 register (PM3)
Port Mode 3 Register is organized as a 4-bit binary register (PM3.0 to PM3.3). PM3 can be used to
determine the operating mode of the output port RE and the clock rate of the serial I/O function. The
PM3 control diagram is shown in Figure 8. The bit descriptions are as follows:

Note: W means write only.
Bit 0 is reserved.
Bit 1 = 0 The output of the port RE is the output of the internal parallel port RT.
= 1 The port RE works as the serial input/output port.
Bit 2 is reserved.
Bit 3 = 0 Serial Tx rate = F
