Input
Data Bus
— D7 - D14 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 - D15and 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 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.

RD

Output
Tri-stated
Read Enable
— RD is asserted during external memory read
cycles. When RD is asserted low, pins D0 - D15 become inputs
and an external device is enabled onto the data bus. When RD is
deasserted high, the external data is latched inside the device.
When RD is asserted, it qualifies the A0 - A23, PS, DS, and CSn
pins. RD can be connected directly to the OE pin of a static RAM
or ROM.
Depending upon the state of the DRV bit in the EMI bus control
register (BCR), RD is
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.
To deactivate the internal pull-up resistor, set the CTRL bit in the
SIM_PUDR register.
