Port mode register 6 (PMR6) controls switching of each pin function of port 6. The switching is
specified in units of bits.
PMR6 is an 8-bit read/write enable register. When reset, PMR6 is initialized to H'00.
Bits 7 to 0: P67/RP7 to P60/RP0 Pin Switching (PMR67 to PMR60)
PMR67 to PMR60 set whether the P6n/RPn pin is used as a P6n I/O pin or an RPn pin for the
realtime output port.
Bit n
PMR6n Description
0 The P6n/RPn pin functions as a P6n I/O pin (Initial value)
1 The P6n/RPn pin functions as an RPn output pin
(n = 7 to 0)
