bit in the FSTAT register all FCCOB parameter fields are locked and cannot be changed by the user until the command completes
(as evidenced by the Memory Controller returning CCIF to 1). Some commands return information to the FCCOB register array.
The generic format for the FCCOB parameter fields in NVM command mode is shown in
available for reading after the CCIF flag in the FSTAT register has been returned to 1 by the Memory Controller. Writes to the
unimplemented parameter fields (CCOBIX = 110 and CCOBIX = 111) are ignored with reads from these fields returning 0x0000.
