System
Applications
In Figure 11, the PSD3XX is configured to interface with Intel’s 80C31, which is a 16-bit
address/8-bit data bus microcontroller. Its data bus is multiplexed with the low-order
address byte. The 80C31 uses signals RD to read from data memory and PSEN to read
from code memory. It uses WR to write into the data memory. It also uses active high reset
and ALE signals. The rest of the configuration bits, as well as the unconnected signals,
are application specific, and thus, user dependent.

Reset
NOTE:
RESET to the PSD3XX must be the output of a RESET chip or buffer.
If RESET to the 80C31 is the output of an RC circuit, a separate buffered RC RESET to the
PSD3XX (shorter than the 80C31 RC RESET) must be provided to avoid a race condition.
