Port D
Functionality and Structure
Port D has three I/O pins. See Figure
31
and
Fig-
ure 32., page 63
. This port does not support Ad-
dress Out mode, and therefore no Control
Register is required. Port D can be configured to
perform one or more of the following functions:
MCU I/O Mode
CPLD Output
External Chip Select (ECS0-
ECS2)
CPLD Input
direct input to the CPLD, no
Input Macrocells (IMC)
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:
PD0
ALE, as address strobe input
PD1
CLKIN, as clock input to the macrocells
flip-flops and APD counter
PD2
CSI, as active Low chip select input. A
High input will disable the Flash memory,
EEPROM, SRAM and CSIOP.
