EMIFA BOOT CONFIGURATION
This pin is multiplexed between EMIFA and the VPBE. At reset, the input state is
sampled to set the EMIFA data bus width (EM_WIDTH). For an 8-bit wide EMIFA
data bus, EM_WIDTH = 0. For a 16-bit wide EMIFA data bus, EM_WIDTH = 1.
After reset, it is video encoder output COUT2 or RGB666/888 Blue output data bit 5
B5.
This pin is multiplexed between DSP boot and the VPBE. At reset, the input state is
sampled to set the DSP boot source DSP_BT. The DSP is booted by the ARM when
DSP_BT=0. The DSP boots from EMIFA when DSP_BT=1.
After reset, it is video encoder output COUT3 or RGB666/888 Blue data bit 6 output
B6.

These pins are multiplexed between EMIFA and the VPBE. At reset, the input states
of AEAW[4:0] are sampled to set the EMIFA address bus width. See the Peripheral
Selection at Device Reset section for details.
After reset, these are video encoder outputs YOUT[0:4] or RGB666/888 Red and
Green data bit outputs G5, G6, G7, R3, and R4.

EMIFA FUNCTIONAL PINS: ASYNC / NOR
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
