Port 4 is a 7-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.
In case of an external bus configuration, Port 4 can be used
to output the segment address lines:
P4.0
A16
Least Significant Segment Addr. Line

P4.6
A22
Most Significant Segment Addr. Line
RD

External Memory Read Strobe. RD is activated for every
external instruction or data read access.
WR/WRL 32
34
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.
READY
33
35
I
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 time waitstates until the pin
returns to a low level.
ALE
34
36
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
35
37
I
External Access Enable pin. A low level at this pin during and
after Reset forces the C161RI to begin instruction execution
out of external memory. A high level forces execution out of
the internal ROM. The C161RI must have this pin tied to ‘0’.
Note:
This pin is expected to be used to accept the
programming voltage for OTP versions of the C161RI.
