Pin Descriptions
IO PORTS
Port A is a 16-bit multiplexed addressdata bus used for
accessing external program and data memory Four associ-
ated bus control signals are available on port B The Ad-
dress Latch Enable (ALE) signal is used to provide timing to
demultiplex the bus Reading from and writing to external
memory are signalled by RD and WR respectively External
memory can be addressed as either bytes or words with the
decoding controlled by two lines Bus High Byte enable
(HBE) and AddressData Line 0 (A0)
Port B is a 16-bit port with 12 bits of bidirectional IO Pins
B10 B11 B12 and B15 are the control bus signals for the
addressdata bus Port B may also be configured via a func-
tion register BFUN to individually allow each bidirectional
IO pin to have an alternate function

Note
Any of these pins can be read by software Therefore unused func-
tions can be used as general purpose inputs notably external enable
lines when the internal serial decoder is used
Port R is an 8-bit bidirectional IO port available for general
purpose IO operations Port R has a direction register to
enable each separate pin to be individually defined as an
input or output It has a data register which contains the
value to be output In addition the Port R pins can be read
directly using the Port R pins address
