I/O/Z
For EMIFA, it is address output EM_A[1].
This pin is multiplexed between VPBE (VENC), EMIFA, and GPIO.
For EMIFA, this is Address output EM_A[0], which is the least
significant bit on a 32-bit word address.
For an 8-bit asynchronous memory, this pin is the 3rd bit of the
address.

Note:
This pin features an internal pulldown (IPD). If this pin is
connected and used as an EMIFA chip select signal, for proper device
operation, an external pullup resistor
must
be used to ensure the
EM_CSx function defaults to an inactive (high) state.
This pin is multiplexed between VPBE (VENC), EMIFA (NAND), and
GPIO.
For EMIFA, this pin is Chip Select 3 output EM_CS3 for use with
NAND flash.
