Port 4
is an 8-bit uni-directional 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.
The
Program Strobe Enable
output is a control signal that enables the
external program memory to the bus during
external fetch operations. It is activated every
one and a half oscillator periods except during
external data memory accesses. Remains high
during internal program execution. This pin
should not be driven during reset operation.
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 one and a half
oscillator periods except during an external
data memory access. When instructions are
executed from internal ROM (EA = 1) the ALE
generation can be disabled by bit EALE in SFR
SYSCON. This pin should not be driven during
reset operation.
External Access Enable
When held at high level, instructions are
fetched from the internal ROM when the PC is
less than 8000
H
. When held at low level, the
C508 fetches all instructions from external
program memory. This pin should not be driven
during reset operation.
