• Name: NFCDATA_Status
• Access: Read
• Reset: 0x00000000
• CMD1: Command Register Value for Cycle 1
When a Read or Write Access occurs, the Physical Memory Interface drives the IO bus with CMD1 field during the Com-
mand Latch cycle 1.
• CMD2: Command Register Value for Cycle 2
When VCMD2 field is set to true, the Physical Memory Interface drives the IO bus with CMD2 field during the Command
Latch cycle 2.
• VCMD2: Valid Cycle 2 Command
When set to true, the CMD2 field is issued after addressing 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.
• CSID: Chip Select Identifier
Chip select used
• NFCEN: NFC Enable
When set to true, The NFC is enabled.
• NFCWR: NFC Write Enable
0: The NFC is in read mode.
1: The NFC is in write mode.
• NFCBUSY: NFC Busy Status Flag
If set to true, it indicates that the NFC is busy.
