Register description
Flash control/status register (FCSR)
This register is reserved for programming using ICP, IAP or other programming methods. It
controls the XFlash programming and erasing operations.
When an EPB or another programming tool is used (in socket or ICP mode), the RASS keys
are sent automatically.
1st RASS Key: 0101 0110 (56h)
2nd RASS Key: 1010 1110 (AEh)
