R/W

This FLASHKEY register is used by table write IAP mode operation. The IAP enable signal

is generated when a specific value is written into this register, e.g., 0xB4. The register is

designed to make sure that IAP operation occurs for flash update. Written into register

value 0XC5. The register is designed to make sure that IAP lock.
