Port 5 is an 8-bit bidirectional I/O port with

internal pullup resistors. Port 5 pins that

have 1's written to them are pulled high by

the internal pullup resistors, and in that

state can be used as inputs. As inputs,

port 5 pins being externally pulled low will

source current

(I IL in the DC characteristics) because of

the internal pullup resistors.

Supply voltage

during normal, idle, and power-down

operation. Internally connected to pin 68.

Ground (0 V)

Supply voltage

during normal, idle, and power-down

operation. Internally connected to pin 37.

Not connected

These pins of the P-MQFP-80 package

must not be connected
