What is the memory map diagram, and the FCU-RAM area mentioned in the ROM chapter of the manual?


It is the area where the dedicated sequencer (FCU) that programs the ROM (flash memory for code storage) and E2 DataFlash (flash memory for data storage) operates.

To perform programming or erasure of the on-chip flash memory, FCU firmware must first be transferred from the FCU firmware area to the FCU-RAM area in advance.

For details, please see the Flash Memory chapter of the User's Manual: Hardware.
