Peripheral Chip Select 6 or Latched A2 may be programmed
to provide a seventh peripheral chip select or to provide an
internally latched A2 signal The address range activating
PCS6 is software-programmable PCS6 A2 does not float
during bus HOLD When programmed to provide latched A2
this pin will retain the previously latched value during HOLD
Data Transmit Receive controls the direction of data flow
through an external data bus transceiver When LOW data is
transferred to the procesor When HIGH the processor
places write data on the data bus
Data Enable is provided as a data bus transceiver output
enable DEN is active LOW during each memory and I O
access (including 80C187 access) DEN is HIGH whenever
DT R changes state During RESET DEN is driven HIGH for
one clock then floated
Not connected To maintain compatibility with future
products do not connect to these pins
