Port D – Functionality and Structure
Port D has two I/O pins (only one pin, PD1, in the
52-pin package). See Figure 57 and Figure 58.
This port does not support Address Out Mode, and
therefore no Control Register is required. Of the
eight bits in the Port D registers, only Bits 2 and 1
are used to configure pins PD2 and PD1.
Port D can be configured to perform one or more
of the following functions:
I
MCU I/O Mode
I
CPLD Output – External Chip Select (ECS1-
ECS2)
I
CPLD Input – direct input to the CPLD, no Input
Macrocells (IMC)
I
Slew rate – pins can be set up for fast slew rate
Port D pins can be configured in PSDsoft Express
as input pins for other dedicated functions:
I
CLKIN (PD1) as input to the macrocells flip-
flops and APD counter
I
PSD Chip Select Input (CSI, PD2). Driving this
signal High disables the Flash memory, SRAM
and CSIOP.
