In Handshake Mode, Port 3 lines P31 and P36 are used as handshake control lines. The
handshake direction is determined by the configuration (input or output) assigned to bit 7
of Port 2 (see
Port 3 (P37-P30). Port 3 is an 8-bit, CMOS-compatible port with four fixed inputs (P33-
P30) and four fixed outputs (P37-P34). These eight lines can be configured by software
for interrupt and handshake control functions. Port 3, Pin 0 is Schmitt- triggered. P31,
P32, and P33 are standard CMOS inputs with single trip point (no Auto Latches) and P34,
P35, P36, and P37 are push-pull output lines. Low EMI output buffers can be globally pro-
grammed by the software. Two on-board comparators can process analog signals on P31
