4. Port mode register 4 (PMR4)
PMR4 is an 8-bit read/write register that controls whether individual port 2 pins are set as CMOS
or NMOS open-drain when 1 is set in PCR.
A 0 setting should be used for this function.
Upon reset, PMR4 is initialized to H'00.
Bit n: NMOS open-drain output select (NMODn)
These bits select NMOS open-drain when pin P2
cleared to 0.
