Figure 1.6.3. Device's internal status after a reset is cleared
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.
Note: When the VCC level is applied to the CNVSS pin, it is 0316 at a reset.
