Figure 22. Port D Structure
Port D – Functionality and Structure
Port D has three I/O pins. See Figure 22 and Fig-
ure 23. Port D can be configured to perform one or
more of the following functions:
I
MCU I/O Mode
I
D
PLD Output – External Chip Selects, ECS0-2
does not consume OMCs
I
CPLD Input – direct input to the CPLD, does not
use IMCs
I
Slew rate – pins can be set up for fast slew rate
Port D pins can be configured in PSDsoft as in-
put pins for other dedicated functions:
I
CLKIN (PD1) as input to the OMCs Flip-flops
I
PSD Chip Select Input (CSI, PD2). Driving this
signal logic High disables the Flash memory,
putting it in standby mode.
External Chip Select.
The DPLD also provides
three External Chip Select outputs (ESC0-2) on
Port D pins that can be used to select external de-
vices as defined in PSDsoft Express. Each Exter-
nal Chip Select consists of one product term that
can be configured active High or Low. The output
enable of the pin is controlled by either the output
enable product term or the Direction Register.
(See Figure 23.) External Chip Selects for Port D
pins do not consume OMCs. External chip select
outputs can also come from the CPLD if chip se-
lect equations are specified in PSDsoft Express for
Ports B or C.
