FUNCTION DESCRIPTION
BANK0 BUS WIDTH
The data bus of BANK0 (nGCS0) should be configured to either 16-bit or 32-bit accordingly. Because the BANK0
works as the booting ROM bank (map to 0x0000_0000), the bus width of BANK0 should be determined before the
first ROM access, which will depend on the logic level of OM[1:0] at Reset.
