A temperature sensor performs A/D conversion for two voltages, an internal reference voltage (sensor 0 on the
Caution The temperature sensor cannot be used when low current consumption mode is set (RMC = 5AH)
The temperature sensor consists of an A/D converter and the following hardware.
• Temperature sensor 0: Outputs the internal reference voltage that depends on the temperature
• Temperature sensor 1: Outputs the internal reference voltage that does not depend on the temperature
