State
Data Bus — D0 - D6 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), D0 - D6 and EMI control signals 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 seven GPIO pins can be individually
programmed as input or output pins.
After reset, these pins default to the EMI Data bus function.
To deactivate the internal pull-up resistor, clear the appropriate
GPIO bit in the GPIOF_PUR register.
Example: GPIOF9, clear bit 9 in the GPIOF_PUR register.
