O The Address Latch Enable
output is used for latching the low-byte of the address into
external memory during normal operation. It is activated
every six oscillator periodes except during an external
data memory access.
If no external memory is used, the ALE signal generation
can be inhibited, reducing system RFI, by clearing
register bit EALE in the SYSCON register.

I External Access Enable
When held at high level, instructions are fetched from the
internal ROM when the PC is less than the size of the
internal ROM : C511

When held at low level, the microcontroller fetches all
instructions from external program memory.

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
application it uses strong internal pullup transistors when
issuing 1s. External pullup resistors are required during
program verification.
