Standard 8051 8-Bit Flash MCU
HT85F2260/HT85F2270/HT85F2280
PnM0/PnM1 Registers – Port Mode Registers
These registers only exist for Ports 0~3. They are used to setup the I/O operating mode of each pin.
As there are four different operating modes for the Port 0~3 pins, each pin has two bits to select
the mode, known as the PnM0 and PnM1 bits. As Ports 4 and 5 only have a single operating mode,
they do not have port mode registers.
