Chip select input (CSI)
Pin PD2 of Port D can optionally be configured in PSDsoft Express as the PSD Module Chip
Select Input, CSI, which is an active-low logic input. By default, pin PD2 does not have the
CSI function.
When the CSI function is specified in PSDsoft Express, the CSI signal is automatically
included in DPLD chip select equations for FSx, CSBOOTx, RS0, and CSIOP. When the CSI
pin is driven to logic ’0’ from an external device, all of these memories will be available for
