I/O
Port 0
is an 8-bit open-drain bidirectional I/O port. Port 0 pins
that have 1s written to them float, and in that state can be
used as high-impendance inputs. Port 0 is also the
multiplexed low-order address and data bus during
accesses to external program or data memory. In this
operating mode it uses strong internal pullup resistors
when issuing 1 s.

I
Hardware Power Down
A low level on this pin for the duration of one machine
cycle while the oscillator is running resets the C509-L.
A low level for a longer period will force the part to power
down mode with the pins floating. There is no internal
pullup resistor connected to this pin.

I/O
Port 5
is an 8-bit quasi-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.
Port 5 can also be switched into a bidirectional mode, in
which CMOS levels are provided. In this bidirectional
mode, each port 5 pin can be programmed individually
as input or output.
Port 5 also serves as alternate function for “Concurrent
Compare” and "Set/Reset compare” functions.
The
output latch corresponding to a secondary function must
be programmed to a one (1) for that function to operate.
The secondary functions are assigned to the pins of port
5 as follows :
