(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
The return values are 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.
Table 19-24
contains the command code, followed by the parameters for this specific Flash command. For details on
the FCCOB settings required by each command, see the Flash command descriptions in
19.3.2.12 Flash Reserved0 Register (FRSV0)
This Flash register is reserved for factory testing.
All bits in the FRSV0 register read 0 and are not writable.
