The port mode register 3 (PMR3) controls function switching of each pin in the port 3.
Switching is specified for each bit.
The PMR3 is a 8-bit readable/writable register and is initialized to H'00 by a reset.
For bits other than 5 to 2, see section 11.5, Port 3.
Bits 5 to 2: P35/PWM3 to P32/PWM0 Pin Switching (PMR35 to PMR32)
These bits set whether the P3n/PWMn pin is used as I/O pin or it is used as 8-bit PWM output
PWMm pin.
Bit n
PMR3n Description
0 P3n/PMWm pin functions as P3n I/O pin (Initial value)
1 P3n/PMWm pin functions as PWMm output pin
(n = 5 to 2, m = 3 to 0)
