(7) Port mode register 13 (PM13)
This register sets port 13 input/output in 1-bit units.
When using the P132/TO03/TI013 pin for timer output, set PM132 and the output latch of P132 to 0.
When using the P131/TI003 and P132/TI013/TO03 pins for timer input, set PM131 and PM132 to 1. At this time,
the output latch of P131 and P132 may be 0 or 1.
PM13 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PM13 to FFH.
