Output
Tri-stated
Input
Program Memory Select
— This signal is actually CS0 in
the EMI, which is programmed at reset for compatibility
with the 56F80x PS signal. PS is asserted low for external
program memory access.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR),
PS is tri-stated when the external
bus is inactive.
Port D GPIO
— This GPIO pin can be individually
programmed as an input or output pin.
CS0 resets to provide the PS function as defined on the
56F80x devices.
To deactivate the internal pull-up resistor, clear bit 8 in the
GPIOD_PUR register.
DS

Input
Data Memory Select
— This signal is actually CS1 in the
EMI, which is programmed at reset for compatibility with
the 56F80x DS signal. DS is asserted low for external data
memory access.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR), DS is tri-stated when the external
bus is inactive.
Port D GPIO
— This GPIO pin can be individually
programmed as an input or output pin.
CS1 resets to provide the DS function as defined on the
56F80x devices.
To deactivate the internal pull-up resistor, clear bit 9 in the
GPIOD_PUR register.
GPIOD0
(CS2)

Tri-stated
Port D GPIO
— These two GPIO pins can be individually
programmed as input or output pins.
Chip Select
— CS2 - CS3 may be programmed within the
EMI module to act as chip selects for specific areas of the
external memory map.
Depending upon the state of the DRV bit in the EMI bus
control register (BCR), CS2 - CS3 are tri-stated when the
external bus is inactive.
At reset, these pins are configured as GPIO.
To deactivate the internal pull-up resistor, clear the
appropriate GPIO bit in the GPIOD_PUR register.
Example: GPIOD0, clear bit 0 in the GPIOD_PUR register.
GPIOD1
