Description
NAND Device Data. No default value. This address space is not to be read from until
data is read from the NAND Flash device. The system will hang if a read is done from
this address space without a prior read from NAND Flash device.
Description
Reserved (Read Only). Returns 0 when read.
NAND Distract Interrupt Enable.
0: Disables the generation of NAND Distract Interrupt.
1: Enables the generation of NAND Distract Interrupt.
NAND Ready Interrupt Mask.
0: Interrupt is masked.
1: Enable NAND Flash device’s RDY/BUSY# signal to generate an interrupt.
Address Latch Enable. FLASH_ALE output signal reflects the value of this bit.
Command Latch Enable. FLASH_CLE output signal reflects the value of this bit.
Chip Enable. CE# signal reflects the value of this bit. The NAND_CS signals from the
Diverse Device determine which CE# is asserted. Keep this bit low during entire NAND
cycle. Writing a 1 to this bit resets the NAND controller.
