x : Nothing is mapped to this bit
? : Undefined
The content of other registers are undefined when the microcomputer is reset. The initial values must therefore be set.
The RAM is undefined at power on. The initial values must therefore be set. When a reset signal is applied while the
CPU is writing a value to the RAM, the value may be set as unknown due to the termination of the CPU access.
Note 1: When the VCC level is applied to the CNVSS pin, it is 0216 at a reset.
Note 2: This register is only exist in flash memory version.
