State
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.
Most designs will want to change the DRV state to DRV = 1
instead of using the default setting.
At 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.
