7.1.5 Registers
Table 7-54 provides a summary of the GPMC registers. All GPMC registers are aligned to 32-bit address
boundaries. All register file accesses, except the GPMC_NAND_DATA_i register, are little-endian. If the
GPMC_NAND_DATA_i register is accessed, the endianness is access-dependent.
In this section, i corresponds to the chip-select number, i = 0 to 6.
