25.16.2.2
• Name: NFCADDR_CMD
• Access: Read-write
• Reset: 0x00000000
• CMD1: Command Register Value for Cycle 1
If NFCCMD is set, when a read or write access occurs, the NFC sends this command.
• CMD2: Command Register Value for Cycle 2
If NFCCMD and VCMD2 field are set to one, the NFC sends this command after CMD1.
• VCMD2: Valid Cycle 2 Command
When set to true, the CMD2 field is issued after the address cycle.
• ACYCLE: Number of Address required for the current command
When ACYCLE field is different from zero, ACYCLE Address cycles are performed after Command Cycle 1. The maximum
number of cycles is 5.
• CSID: Chip Select Identifier
Chip select used
• NFCEN: NFC Enable
When set to true, the NFC will automatically read or write data after the command.
• NFCWR: NFC Write Enable
0: The NFC reads data from the NAND Flash.
1: The NFC writes data into the NAND Flash.
• NFCCMD: NFC Command Enable
If set to true, CMD indicates that the NFC shall execute the command encoded in the NFCADDR_CMD.
