Function
Port 5
is a bidirectional I/O port with internal
pull-up resistors. Port 5 pins that have
1 s written to them are pulled high by
the internal pull-up resistors, and in that
state can be used as inputs. As inputs,
port 5 pins being externally pulled low
will source current (I
characteristics) because of the internal
pull-up resistors. This port also serves
the alternate function "Concurrent
Compare". The secondary functions
are assigned to the port 5 pins as
follows:
– CCM0 (P5.0): concurrent compare 0
– CCM1 (P5.1): concurrent compare 1
– CCM2 (P5.2): concurrent compare 2
– CCM3 (P5.3): concurrent compare 3
– CCM4(P5.4): concurrent compare 4
– CCM5 (P5.5): concurrent compare 5
– CCM6 (P5.6): concurrent compare 6
– CCM7(P5.7): concurrent compare 7
Oscillator Watchdog Enable
A high level on this pin enables the
oscillator watchdog. When left
unconnected this pin is pulled high by a
weak internal pull-up resistor. When
held at low level the oscillator watchdog
function is off.
