Each bit of PORTm.PMR corresponds to each pin of port m; pin function can be specified in 1-bit units.
Bits corresponding to port m on the 48 pin-product but which do not exist on a product with fewer than 48 pins are
reserved. Write 0 to these bits.
The bit corresponding to a pin that does not exist is reserved. A reserved bit is read as 0. The write value should be 0.
