(3) Port mode register 7 (PM7)
224
This register sets port 7 input/output in 1-bit units.
When using the P72/TO50/TI50 and P73/TI51/TO51 pins for timer output, clear PM72, PM73, and the output
latches of P72 and P73 to 0.
When using the P72/TO50/TI50 and P73/TI51/TO51 pins for timer input, set PM72 and PM73 to 1. At this time,
the output latches of P72 and P73 can be either 0 or 1.
PM7 is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets PM7 to FFH.
