x : Nothing is mapped to this bit
? : Undefined
The content of other registers and RAM is undefined when the microcomputer is reset. The initial values
must therefore be set.
Note1: When the VCC level is applied to the CNVSS pin, it is 0216 at a reset.
Note2: This register is only exist in flash memory version.
