5. Operation
This section explains the operation of the wild register.
This function is used to patch the flash area. Because the enable register is initialized by reset, this register
needs to be set on each reset when being used.
The setting addresses need to be set so that they do not overlap each other. When addresses overlap, the
reading value is undefined.
The data's byte line is the big endian.
The target area to replace is the Flash area only.
