3-5. POWER FAIL CIRCUIT
Power fail generated by a circuit using the PF DTC voltage.
When power is on and the system is operating normally, the power fall signal stays at a higher
voltage than 1.21V.
The CPU watches power failure signals all the time. When power is on, PF -5pin at High level.
When power down and CPU(U1)27pin voltage goes down lower than PF detection voltage(=1.21V),
low-power-supply detector circuit of the CPU works and execute PF.
