12.5 A19/CSI
This pin is configured using PSDsoft to be either a chip select for the entire PSD device or
an additional PAD input. If your MCU can generate a chip-select signal, and you wish to
save power, use the PSD chip select feature. Otherwise, use this pin as an address or logic
input.
J
When configured as CSI (active-low PSD chip select): a low on this pin keeps the PSD
in normal operation. However, when a high is detected on the pin, the PSD
enters Power-down Mode. See Tables 7A and 7B for information on signal states
during Power-down Mode. See section 16 for details about the reduction of power
consumption.
J
When configured as A19, the pin can be used as an additional input to the PADs.
It can be used for address or logic. It can also be ALE/AS dependent or a transparent
input, which is determined by your PSDsoft design file. In A19 mode, the PSD is always
enabled.
