Note 1 : When the VCC level is applied to the CNVSS pin, it is 0316 at a reset.
control register
U : This bit is the cold start / warm start flag, is set to “0” at power on reset (refer to Page 71).
! : 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.
