RD
25
O
External Memory Read Strobe. RD is activated for every
external instruction or data read access.
WR/
WRL
26
O
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.
ALE
27
O
Address Latch Enable Output. Can be used for latching the
address into external memory or an address latch in the
multiplexed bus modes.
EA
28
I
External Access Enable pin. A low level at this pin during and
after Reset forces the C161S 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’.

IO
PORT0 consists of the two 8-bit bidirectional I/O ports P0L
and P0H. 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.
In case of an external bus configuration, PORT0 serves as
the address (A) and address/data (AD) bus in multiplexed
bus modes and as the data (D) bus in demultiplexed bus
modes.
Demultiplexed bus modes:
Data Path Width:
8-bit
16-bit
P0L.0 – P0L.7:
D0 – D7
P0H.0 – P0H.7:
I/O
D8 – D15
Multiplexed bus modes:
Data Path Width:
8-bit
16-bit
P0L.0 – P0L.7:
AD0 – AD7
P0H.0 – P0H.7:
A8 – A15
AD8 – AD15
