Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
Chip Select — CS2 may be programmed within the EMI module
to act as a chip select for specific areas of the external memory
map. Depending upon the state of the DRV bit in the EMI Bus
Control Register (BCR),CS2 is tri-stated when the external bus is
inactive.
FlexCAN2 Transmit Data — CAN output.
At reset, this pin is configured as GPIO. This configuration can be
changed by setting bit 0 in the GPIO_D_PER register, then
change bit 4 in the SIM_GPS register to select the desired
peripheral function.
To deactivate the internal pull-up resistor, clear bit 0 in the
GPIOD_PUR register.
Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
Chip Select — CS3 may be programmed within the EMI module
to act as a chip select for specific areas of the external memory
map.
Depending upon the state of the DRV bit in the EMI Bus Control
Register (BCR), CS3 is tri-stated when the external bus is
inactive.
FlexCAN2 Receive Data — This is the CAN input. This pin has
an internal pull-up resistor.
At reset, this pin is configured as GPIO. This configuration can be
changed by setting bit 1 in the GPIO_D_PER register, then
change bit 5 in the SIM_GPS register to select the desired
peripheral function.
To deactivate the internal pull-up resistor, clear bit 1 in the
GPIOD_PUR register.
