18.3.1.11.1 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
