(a)MCU detects RMS value of bypass 3-phase voltage via Vbyp_R (89), Vbyp_S (91) and Vbyp_T (93).

(b)MCU detects RMS value of main input 3-phase voltage via Vin_R (92), Vin_S (94) and Vin_T (96).

(c)MCU detects the bypass frequency and zero crossing via BYPZO_R (12) at falling edge.

(d)MCU detects the main input frequency and zero crossing via INPZO_R (14) at falling edge.
