Building NFC Address Command Example.
The base address is made of address 0x60000000 + NFCCMD bit set = 0x68000000.
Page read operation example:
// Build the Address Command (NFCADDR_CMD)
AddressCommand = (0x60000000
*AddressCommand = (Col. Add2
// Set the Address for Cycle 0
SMC_ADDR = Col. Add1
// Write command with the Address Command built above
NFCCMD=1 | // NFC Command Enable
ACYCLE= 5 |
VCMD2=1
CMD2=0x30
CMD1=0x0)
NFCWR=0
NFCEN=1
CSID=1
