Flash Write Data Register
This register specifies write data of the built-in Flash.
When setting it in the unit of byte, conform to the order of higher order byte - lower order byte. If you reverse
the order, data cannot be correctly written.
Writing to the lower order byte updates the Flash Address Register to the next write address.
