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.
This register is used to pass Flash commands, addresses, and data during C2 Flash
accesses. Valid commands are listed below.
