SPC560B40L3 Analog watchdog for pulse transition period detection.

Hello,

I want to sense period of 4 pulses using Analog Watchdog. I am using SPC560B40L3(100Pin controller). My requirement is to sense the Analog window voltage.

Ex. Square wave Pulse varies from 0.5V to 4.5V. And if I put my thresholds for every pulse on 1V(LOW threshold) & 4V(HIGH threshold). Is it possible to detect individual pulse transition period measurement?

Thanks,

Ashok

    Thanks for response.

    I think by using IPM I'll be able to measure total pulse not half pulse(High/Low Period) please correct me if I am wrong. By using Analog watch I want to measure half pulse period for multiple channels.
