Programmable Registers
15.4.2 GPMI Compare Register (HW_GPMI_COMPARE)
The GPMI compare register specifies the expect data and the xor mask for comparing to
the status values read from the device. This register is used by the Read and Compare
command.
Address:

Selects which chip select is active for this command.
In NAND mode, use A0 for CLE and A1 for ALE.

0x1
0x2
0= Address does not increment.
1= Increment address.
In NAND mode, the address will increment once, after the first cycle (going from CLE to ALE).

Number of words (8 bit wide) to transfer for this command. A value of zero will transfer 64K words.
16-bit mask which is applied after the read data is XORed with the REFERENCE bit field.
16-bit value which is XORed with data read from the NAND device.
