Reset:
• SMCSTS: NAND Flash Controller status (this field cannot be reset)
0: NAND Flash Controller is disabled.
1: NAND Flash Controller is enabled.
• RB_RISE: Selected Ready Busy Rising Edge Detected
When set to one, this flag indicates that a rising edge on Ready/Busy Line has been detected. This flag is reset after a sta-
tus read operation. The Ready/Busy line selected is the decoding of the set NFCCSID, RBNSEL fields.
• RB_FALL: Selected Ready Busy Falling Edge Detected
When set to one, this flag indicates that a falling edge on Ready/Busy Line has been detected. This flag is reset after a sta-
tus read operation. The Ready/Busy line is selected through the decoding of the set NFCSID, RBNSEL fields.
• NFCBUSY: NFC Busy (this field cannot be reset)
When set to one this flag indicates that the Controller is activated and accesses the memory device.
• NFCWR: NFC Write/Read Operation (this field cannot be reset)
When a command is issued, this field indicates the current Read or Write Operation. This field can be manually updated
with the use of the SMC_CTRL register.
• NFCSID: NFC Chip Select ID (this field cannot be reset)
When a command is issued, this field indicates the value of the targeted chip select. This field can be manually updated
with the use of the SMC_CTRL register.
• XFRDONE: NFC Data Transfer Terminated
When set to one, this flag indicates that the NFC has terminated the Data Transfer. This flag is reset after a status read
operation.
• CMDDONE: Command Done
When set to one, this flag indicates that the NFC has terminated the Command. This flag is reset after a status read
operation.
