Data Bus — D7 - D14 specify part of the data for external program
or data memory accesses.
Most designs will want to change the DRV state to DRV = 1 instead of
using the default setting.
Port F GPIO — These eight 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.
