Control
nPWM CMP0 Linkage
oCMP0 output restart a new PWM cycle
oCMP0 is able to delay the trigger signal (max 8us @ 8MHz)
nPower control
oMonitor System V
oMonitor System Iby OPA and ADC
oChange PWM duty cycle to change the IH cooker power
oProtection
nIGBT Over VCMP output falling edge stops current PWM output
                               Restart at the next CMP0 trigger ,PWMDATA= PWMPDATA
nSurge/Over I CMP output falling edge stops current PWM output
                               Restart when SW unlock
nPWM anti-miss-triggersetting minimum interval between 2 PWM cycle
nCMP0 output filter
nOver TemperatureMonitor the temperature of IGBT and PAN
nPan DetectIGBT on (set PWM as IO)Count CMP0 Interrupts
