issue with WAVEFSV1, WAVEFSI1, WAVEFSI2 in MSP430FE423A

Hi All,

My WAVEFSV1, WAVEFSI1 and WAVEFSI2 is stuck at zero 0x0000 all time in MSP430FE423A microcontroller.

I can assure that ESPEN bit in ESPCTL is set to '1' (thus ESP430 is enabled)

                           ESPSUSP bit in ESPCTL is reset to '0' (thus ESP430 is not suspended).

I am giving 1.2Vp-p, 50 Hz signal from signal generator on the I1+/-, I2+/-, V1+/-.

I dont know how to debug. What else needs to be checked and how? ADC? Any other control register?

Please help

Thanks in advance for advise,

Regards,
