How to configure the I/O ports

To configure the I/O ports, use the information in

Table 3 and Table 4 and the Port Bit Configuration

Table in the I/O Ports Chapter on page 81.

I/O note = The hardware characteristics fixed for

each port line in Table 3.

All I/O inputs have Schmitt trigger fixed by hard-

ware so selecting CMOS or TTL input by software

has no effect, the input will always be Schmitt Trig-

ger. In particular, the Schmitt Triggers present on

the P5[7:2] pins have a standard hysteresis

whereas the remaining pins have Schmitt Triggers

with High Hysteresis (refer to Electrical Specifica-

tions).

Alternate Functions (AF) = More than one AF

cannot be assigned to an external pin at the same

time:
