System
Applications
In Figure 10, the PSD211R 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
(not shown) are application specific and, thus, user dependent.

All other configuration bits may vary according to the application requirements.
NOTE:
RESET to the PSD211R 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
PSD211R (shorter than the 80C31 RC RESET) must be provided to avoid a race condition.
