13.3.2.11.1 FCCOB - NVM Command Mode
NVM command mode uses the indexed FCCOB register to provide a command code and its relevant
parameters to the Memory Controller. The user first sets up all required FCCOB fields and then initiates
the command’s execution by writing a 1 to the CCIF bit in the FSTAT register (a 1 written by the user
clears the CCIF command completion flag to 0). When the user clears the CCIF 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
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 13-23
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
