Output
Tri-stated
Input
Data Bus
— D15 specifies part of the data for external
program or data memory accesses.
Port F GPIO
— This GPIO pin can be individually
programmed as an input or output pin.
At reset, this pin defaults to the data bus function.
To deactivate the internal pull-up resistor, clear bit 8 in the
GPIOF_PUR register.
RD
45
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 - A16, 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.
To deactivate the internal pull-up resistor, set the CTRL bit
in the SIM_PUDR register.
WR
44
Output
Tri-stated
Write Enable
— WR is asserted during external memory
write cycles. When WR is asserted low, pins D0 - D15
become outputs and the device puts data on the bus.
When WR is deasserted high, the external data is latched
inside the external device. When WR is asserted, it
qualifies the A0 - A16, PS, DS, and CSn pins. WR can be
connected directly to the WE pin of a static RAM.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR), WR is tri-stated when the external bus
is inactive.
To deactivate the internal pull-up resistor, set the CTRL bit
in the SIM_PUDR register.
