3.5.8 Port 7 (P70 - P73)
Port 7 is a 4-bit general-purpose I/O port. I/O can be set on bit

71 as an 8-bit timer output (TO1), Port 72 as a PWM0 output
(TO2), and Port 73 as a PWM1 output (TO3) pin. Writing 1 in
the corresponding bit of the Port 7 function register (P7FC)
enables output of the timer. Resetting resets the function regis-
ter P7FC value to 0, and sets all bits to ports.
