Original 50/96
capacitor is charged through resistor R163. This voltage is fed to regula-
tor N100 shutdown input (pin 3) through transistor V162.The 5V reference
supply is generated by regulator N100.If the processor stops the voltage
across the capacitor increases and the regulator is switched off.
