Tri-stated
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), CS0 is tri-stated when the external bus is inactive.
CS0 resets to provide the PS function as defined on the 56F80x
devices.
Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
To deactivate the internal pull-up resistor, clear bit 8 in the
GPIOD_PUR register.

Tri-stated
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), A0 - A23 and EMI control signals are tri-stated
when the external bus is inactive.
CS1 resets to provide the DS function as defined on the 56F80x
devices.
Port D GPIO — This GPIO pin can be individually programmed
as an input or output pin.
To deactivate the internal pull-up resistor, clear bit 9 in the
GPIOD_PUR register.
