Tri-stated
Data Bus — D7 - D15 specify part of the data for external
program or data memory accesses.
Depending upon the state of the DRV bit in the EMI bus control
register (BCR), D7 - D15 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.
Port F GPIO — These nine GPIO pins can be individually
programmed as input or output pins.
At reset, these pins default to data bus functionality.
To deactivate the internal pull-up resistor, clear the appropriate
GPIO bit in the GPIOF_PUR register.
Example: GPIOF0, clear bit 0 in the GPIOF_PUR register.
