Address Bus — A6 - A7 specify two of the address lines for
external program or data memory accesses.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR), A6 - A7 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 E GPIO — These two GPIO pins can be individually
programmed as input or output pins.
After reset, the default state is Address Bus.
To deactivate the internal pull-up resistor, clear the
appropriate GPIO bit in the GPIOE_PUR register.
Example: GPIOE2, clear bit 2 in the GPIOE_PUR register.

Address Bus— A8 - A15 specify eight of the address lines
for external program or data memory accesses.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR), A8 - A15 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 A GPIO — These eight GPIO pins can be individually
programmed as input or output pins.
After reset, the default state is Address Bus.
To deactivate the internal pull-up resistor, clear the
appropriate GPIO bit in the GPIOA_PUR register.
Example: GPIOA0, clear bit 0 in the GPIOA_PUR register.
