(6) Port mode register 3 (PM3)
This register sets port 3 input/output in 1-bit units.
When using the P34/TI52/TI010/TO00/RTC1HZ/INTP1 pin for timer output, set PM34 and the output latches of
P34 to 0.
When using the P33/TI000/RTCDIV/RTCCL/BUZ/INTP2 and P34/TI52/TI010/TO00/RTC1HZ/INTP1 pins for timer
input, set PM33 and PM34 to 1. At this time, the output latches of P33 and P34 may be 0 or 1.
PM3 can be set by a 1-bit or 8-bit memory manipulation instruction.
