Note
Note Set P130 to high-level output by software.
Remarks 1. When reset is effected, P130 outputs a low level. If P130 is set to output a high level immediately
after reset is effected, the output signal of P130 can be dummy-output as the reset signal to the CPU.
2. For the reset timing of the power-on-clear circuit and low-voltage detector, see CHAPTER 18
POWER-ON-CLEAR CIRCUIT and CHAPTER 19 LOW-VOLTAGE DETECTOR.
