Function
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
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
(I
