Port D GPIO — These six GPIO pins can be individually
programmed as input or output pins.
Chip Select — CS2 - CS7 may be programmed within the EMI
module to act as chip selects for specific areas of the external
memory map. Depending upon the state of the DRV bit in the
EMI bus control register (BCR), CS2 - CS7 are tri-stated when
the external bus is inactive.
After reset, these pins are configured as GPIO.
To deactivate the internal pull-up resistor, clear the appropriate
GPIO bit in the GPIOD_PUR register.
Example: GPIOD0, clear bit 0 in the GPIOD_PUR register.
Transmit Data — SCI0 transmit data output
Port E GPIO — This GPIO pin can be individually programmed
as an input or output pin.
After reset, the default state is SCI output.
To deactivate the internal pull-up resistor, clear bit 0 in the
GPIOE_PUR register.
Receive Data — SCI0 receive data input
Port E GPIO — This GPIO pin can be individually programmed
as an input or output pin.
After reset, the default state is SCI output.
To deactivate the internal pull-up resistor, clear bit 1 in the
GPIOE_PUR register.
Transmit Data — SCI1 transmit data output
Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
After reset, the default state is SCI output.
To deactivate the internal pull-up resistor, clear bit 6 in the
GPIOD_PUR register.
