I
Hardware Power Down
A low level on this pin for the duration of
one machine cycle while the oscillator is
running resets the SAB 80C517A. A low
level for a longer period will force the part to
Power Down Mode with the pins floating.

I
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
IL
, in the DC characteristics)
because of the internal pull-up resistors.
This port also serves the alternate function
"Concurrent Compare" and "Set/Reset
Compare". The secondary functions are
assigned to the port 5 pins as follows:
– CCM0 to CCM7 (P5.0 to P5.7):
concurrent compare or Set/Reset

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.
