12.4 Interrupt Inputs 
The W79E8213 series have total 10 interrupt sources with two individual interrupt inputs sources. 
They are IE0, IE1, BOF, EDF, WDT, TF0, TF1, BKF and ADC. Two interrupt inputs are identical to 
those present on the standard 80C51 microcontroller as show in below figures. 
If an external interrupt is enabled when the W79E8213 series are put into Power-down or Idle mode, 
the interrupt will cause the processor to wake up and resume operation.
