9.2.2 PSD4XX Interface To a Multiplexed Bus
Figure 20 shows a typical connection to a microcontroller with a multiplexed bus. The
ADIO port of the PSD4XX is connected directly to the microcontroller address/data bus
(AD0-AD15 for 16 bit bus). The ALE input signal latches the address lines internally. In a
read bus cycle, data is driven out through the ADIO Port transceivers after the specified
access time. The internal ADIO Port connection for a 16 bit multiplexed bus is shown in
Figure 21. The ADIO Port is in tri-state mode if none of the PSD4XX internal devices are
selected.
9.2.3 PSD4XX Interface To Non-Multiplexed Bus
Figure 22 shows a PSD4XX interfacing to a microcontroller with a non-multiplexed
address/data bus. The address bus is connected to the ADIO Port, and the data bus is
connected to Port C and/or Port D, depending on the bus width. There is no need for the
ADIO Port to latch the address internally, but the user is offered the option to do so in the
PSD4XX PSDsoft Software. The data Ports are in tri-state mode when the PSD4XX is not
accessed by the microcontroller.
