I/O PORT MODE

The port direction is programmed by PnM register. Port 0 is always input mode. Port 1,2,4 and 5 can select input or

output direction.

Bit[5:0]

P5[5:0]M: P5.0~P5.5 I/O direction control bit.

0 = input mode

1 = output mode.

The each bit of PnM is set to “0”, the I/O pin is input mode. The each bit of PnM is set to “1”, the I/O pin is output mode.

Input mode is with pull-up resistor controlled by setting @SET_UP macro. The output mode disables the pull-up

resistors no matter pull-up resistors is set or not.

The PnM registers are read/write bi-direction registers. Users can program them by bit control

instructions (B0BSET, B0BCLR).
