Port D – functionality and structure
Port D has two I/O pins (only one pin, PD1, in the 52-pin package). See
Figure
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:
●
●
●
●
Port D pins can be configured in PSDsoft Express as input pins for other dedicated
functions:
●
●
MCU I/O mode
CPLD Output – External Chip Select (ECS1-ECS2)
CPLD Input – direct input to the CPLD, no Input Macrocells (IMC)
Slew rate – pins can be set up for fast slew rate
CLKIN (PD1) as input to the macrocells flip-flops and APD counter
PSD Chip Select Input (CSI, PD2). Driving this signal High disables the Flash memory,
SRAM and CSIOP.
66. This port does not support Address Out mode, and therefore no Control Register
