Figure 1.5.3. Device's internal status after a reset is cleared
x : Nothing is mapped to this bit
? : Undefined
Note 1: When the VCC level is applied to the CNVSS pin, it is 0316 at 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: Channel CAN1 is not available for M16C/6N1 group.
