16.3.6 Port 6
Port 6 is an 8-bit input/output port in which input or output can be specified in 1-bit units. Each port bit
can be independently configured to port input, port output or peripheral function
This register can be read or written in 1-bit and 8-bit units.

Remark:
In Input Mode: When the P6 register is read, the pin levels at that time are read. Writing to
In Output Mode:When the P6 register is read, the values of P6 are read. Writing to the P6
Besides functioning as a port, in control mode, it also can operate as the serial interface (CSI2) or as
external interrupt request input.
Notes: 1. If using peripheral functions, the direction setting for the respective port bit is not forced
automatically. Port bit direction has to be programmed according to the peripheral function
requirement by setting the port mode register.
2. The reset value of register P6 is 00H. Due to the input mode of the port after reset, the read
input value is determined by the port pins.
