FPCTL: FLASH Programming Control Register
This register is used to enable FLASH programming via the C2 interface. To enable C2 FLASH
programming, the following codes must be written in order: 0x02, 0x01. Note that once C2 FLASH
programming is enabled, a system reset must be issued to resume normal operation.
FPDAT: C2 FLASH Programming Data Register
