Port 2 (P27–P20)
Port 2 is an 8-bit, bidirectional, CMOS-compatible I/O port (see
eight I/O lines can be independently configured under software control as inputs
or outputs. Port 2 is always available for I/O operation. A software option is avail-
able to connect eight 200 K
grammed as outputs are globally programmed as either push-pull or open-drain.
Port 2 can be placed under handshake control. In this configuration, Port 3 lines,
P31 and P36 are used as the handshake controls lines /DAV2 and RDY2. The
handshake signal assignment for Port 3, lines P31 and P36 is dictated by the
direction (input or output) assigned to Bit 7, Port 2.
