NAME

NO.

This pin is multiplexed between EMIFA (NAND) and GPIO.

For EMIFA (NAND), this pin is Chip Select 3 output EM_CS3 for use

with NAND flash.

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 EMIFA (NAND) and GPIO.

For EMIFA (NAND), it is Chip Select 4 output EM_CS4 for use with

NAND flash.
