80C31
Figure
21
shows the bus interface for the 80C31,
which has an 8-bit multiplexed address/data bus.
The lower address byte is multiplexed with the
data bus. The MCU control signals Program Se-
lect Enable (PSEN, CNTL2), Read Strobe (RD,
CNTL1), and Write Strobe (WR, CNTL0) may be
used for accessing the internal memory and I/O
Ports blocks. Address Strobe (ALE/AS, PD0)
latches the address.
