Description
ADIO0-7
30-37
I/O
This is the lower Address/Data port. Connect your MCU
address or address/data bus according to the following rules:
1. If your MCU has a multiplexed address/data bus where
the data is multiplexed with the lower address bits,
connect AD[0:7] to this port.
2. If your MCU does not have a multiplexed address/data
bus, or you are using an 80C251 in page mode, connect
A[0:7] to this port.
3. If you are using an 80C51XA in burst mode, connect
A4/D0 through A11/D7 to this port.
ALE or AS latches the address. The PSD drives data out only
if the read signal is active and one of the PSD functional
blocks was selected. The addresses on this port are passed
to the PLDs.
ADIO8-15
39-46
I/O
This is the upper Address/Data port. Connect your MCU
address or address/data bus according to the following rules:
1. If your MCU has a multiplexed address/data bus where
the data is multiplexed with the lower address bits,
connect A[8:15] to this port.
2. If your MCU does not have a multiplexed address/data
bus, connect A[8:15] to this port.
3. If you are using an 80C251 in page mode, connect
AD[8:15] to this port.
4. If you are using an 80C51XA in burst mode, connect
A12/D8 through A19/D15 to this port.
ALE or AS latches the address. The PSD drives data out only
if the read signal is active and one of the PSD functional
blocks was selected. The addresses on this port are passed
to the PLDs.
CNTL0
47
I
The following control signals can be connected to this port,
based on your MCU:
1. WR — active-low write input.
2. R_W — active-high read/active low write input.
This port is connected to the PLDs. Therefore, these signals
can be used in decode and other logic equations.
CNTL1
50
I
The following control signals can be connected to this port,
based on your MCU:
1. RD — active-low read input.
2. E — E clock input.
3. DS — active-low data strobe input.
4. PSEN — connect PSEN to this port when it is being used
as an active-low read signal. For example, when the
80C251 outputs more than 16 address bits, PSEN is
actually the read signal.
This port is connected to the PLDs. Therefore, these
signals can be used in decode and other logic equations.
