I/O
Port 4
is an 8-bit quasi-bidirectional I/O port with internal
pull-up resistors. Port 4 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 4 pins being externally pulled low will source
current (I IL, in the DC characteristics) because of the
internal pull-up resistors.

Power saving mode enable/Start watchdog timer
A low level at this pin allows the software to enter the
power saving modes(idle mode, slow down mode
and power down mode). It is impossible to enter the
software controlled power saving modes if this pin is
held at high level.
A high level during the reset performs an automatic
start of watchdog timer immidiately after reset.
When left unconnected this pin is pulled high by a
weak internal pull-up resistor.

RESET
A low level on this pin for the duration of two machine
cycles while the oscillator is running resets the
C515. A small internal pullup resistor permits power-
on reset using only a capacitor connected to VSS .

Port 6
is an 8-bit unidirectional input port to the A/D
converter. Port pins can be used for digital input, if
voltage levels simultaneously meet the
specifications for high/low input voltages and for the
eight multiplexed analog inputs.
