Notes:
* 1. Reference data only, not tested.
* 2. Power-on Reset circuit detects the rising edge of VDD, resets the internal circuit, and initializes
the registers. After Power-on reset, Stand-by Mode is selected.
* 3. The condition that POR surely works at the power-up the power-up again after power supply goes
down. Unless this condition is satisfied, the reset may not be correctly performed.
