Port 4 is an 8-bit bidirectional I/O port. It is bit-wise
programmable for input or output via direction bits.
For a pin configured as input, the output driver is put
into high-impedance state. Port 4 can be used to
output the segment address lines:
A16
Least Significant Segment Address Line
A17

A18
Segment Address Line
A19

A20

A21

External Memory Read Strobe. RD is activated for
every external instruction or data read access.
External Memory Write Strobe. In WR-mode this pin
is activated for every external data write access. In
WRL-mode this pin is activated for low byte data
write accesses on a 16-bit bus, and for every data
write access on an 8-bit bus. See WRCFG in register
SYSCON for mode selection.
Ready Input. When the Ready function is enabled, a
high level at this pin during an external memory
access will force the insertion of memory cycle
waitstates until the pin returns to a low level.
An internal pullup device holds this pin high when
nothing is driving it.
Address Latch Enable Output. Can be used for
latching the address into external memory or an
address latch in the multiplexed bus modes.
External Access Enable pin. A low level at this pin
during and after Reset forces the C165 to begin
instruction execution out of external memory. A high
level forces execution out of the internal program
memory.
“ROMless” versions must have this pin tied to ‘0’.
