Function
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.
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 C164CI to begin instruction execution
out of external memory. A high level forces execution out of
the internal ROM.
Note: This pin also accepts the programming voltage for OTP
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 and data (AD) bus.
