Port C – functionality and structure
Port C can be configured to perform one or more of the following functions (see Figure 28):
MCU I/O mode
CPLD Output – McellBC7-McellBC0 outputs can be connected to port B or port C.
CPLD input – via the input macrocells (IMC)
Address In – Additional high address inputs using the input macrocells (IMC).
In-system programming (ISP) – JTAG port can be enabled for programming/erase of
for more information on JTAG programming).
Open Drain – port C pins can be configured in Open Drain mode
Port C does not support Address Out mode, and therefore no Control register is required.
Pin PC7 may be configured as the DBE input in certain MCU bus interfaces.

Port D – functionality and structure
Port D has three I/O pins. See Figure 29 and Figure 30. This port does not support Address
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
