4.40.3.2.11
The FCCOB is an array of six words addressed via the CCOBIX index found in the FCCOBIX register. Byte wide reads and writes
are allowed to the FCCOB register.
4.40.3.2.11.1
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
