This pin is multiplexed between EMIFA and HPI.
For EMIFA, this pin is Chip Select 2 output EM_CS2 for use with asynchronous
memories (i.e. NOR flash) or NAND flash. This is the chip select for the default boot
and ROM boot modes.
For EMIFA, this pin is Chip Select 3 output EM_CS3 for use with asynchronous
memories (i.e. NOR flash) or NAND flash.
This pin is multiplexed between EMIFA, GPIO, and VLYNQ. For EMIFA, it is Chip
Select 4 output EM_CS4 for use with asynchronous memories (i.e., NOR flash) or
NAND flash.
This pin is multiplexed between EMIFA, GPIO, and VLYNQ. For EMIFA, it is Chip
Select 5 output EM_CS5 for use with asynchronous memories (i.e., NOR flash) or
NAND flash.
