Port 3 (P37–P31)
Port 3 is a 7-bit, CMOS-compatible fixed I/O port (see Figure 13). Port 3 consists
of three fixed input (P33–P31) and four fixed output (P37–P34), which can be con-
figured under software control for interrupt and as output from the counter/timers.
P31, P32, and P33 are standard CMOS inputs; P34, P35, P36, and P37 are push-
pull outputs.
