Note 1: When the VCC level is applied to the CNVSS pin, it is 0216 at a reset.
The RAM is indeterminate at power on. The initial value must therefore be defined. When a reset signal is input while the CPU is writing a value to the RAM,
the value may be changed to an unintended value.
Note 2: These registers are available on the flash version only.
Note 3: Channel CAN1 is not available for M16C/6N1 group.
