Hi,

We need pulse width measurement feature and PWM generation feature on same pin. Is FLEXIO or EMIOS which is best suit for this need?

Can we measure pulse width using FLEXIO input capture? We are planning to use FLEXIO module as a SPC SENT transmitter emulator. In SENT SPC after receiving trigger pulse we will start sent transmission, as per the requirement I need to measure the trigger pulse width.

Below is the trigger pulse sample. Can we measure below pulse width using FLEXIO input capture mode?
