CHAPTER 2: POWER SUPPLY AND INITIAL RESET
2.2.3 Oscillation detection circuit
The oscillation detection circuit outputs the initial reset signal at power-on until the oscillation circuit
starts oscillating, or when the oscillation circuit stops oscillating for some reason.
Note: Use the reset terminal or K00–K03 simultaneous low input for power-on reset because the
circuit may not work due to chattering when the power is turned on.
The oscillation detection function cannot be used when the mask option is selected as follows:
- When CR oscillation circuit and the SLEEP function are selected in the S1C6N3B0.
- When the SLEEP function is selected in the S1C6A3B0.
2.2.4 Internal register following initialization
An initial reset initializes the CPU as shown in the table below.
