Tri-stated
Output
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.
