Hello, we have an interphone project using MCIMX7D3EVK10SD with external 32.768KHz and 24MHz crystals. We want to make PWM pin of iMX7D output 32K clock to BT and audio codec. But our softwarer engineer don't know how to configure PWM pin. So we need your help.
1: Can PWM pin output 32K clock?
2: How can we check the external 32.768KHz crystal, working, or not?
