I
External Access Enable
When held high, the SAB 80C515A executes
instructions from the internal ROM as long as
the PC is less than 32768. When held low, the
SAB 80C515A fetches all instructions from
external program memory. For the SAB
80C515A this pin must be tied low.

I/O
Port 0
is an 8-bit open-drain bidirectional I/O port.
Port 0 pins that have 1's written to them float,
and in that state can be used as high-
impedance inputs.
Port 0 is also the multiplexed low-order
address and data bus during accesses to
external program and data memory. In this
application it uses strong internal pullup
resistors when issuing 1's.
Port 0 also outputs the code bytes during
program verification in the SAB 80C515A.
External pullup resistors are required during
program verification.
P5.7-P5.0 60-67
60-67
I/O
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
(
I
IL
in the DC characteristics) because of the
internal pullup resistors.

Hardware Power Down
A low level on this pin for the duration of one
machine cycle while the oscillator is running
resets the SAB 80C515A.
A low level for a longer period will force the
part to Power Down Mode with the pins float-
ing. (
