RT 1062 PWM and UART Problem

[EthanKu]

1. if PWM module is used for the input function , do we select whether an PWM module includes a timer or not ? and what is different on PWM module with /without a timer?

2. do UART have a SWAP SW setting by TX and RX if a wrong connection occurs

Hi @EthanKu 

   Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

Answer your questions:

1. if PWM module is used for the input function , do we select whether an PWM module includes a timer or not ? and what is different on PWM module with /without a timer?

=>Answer: If you select the pin as the PWM function, it is not the TMR pin.

As you know, PWM and TMR is totally the different peripheral module.

So, if you select it as the PWM in pinmux, then it is the PWM pin.

2. Do UART have a SWAP SW setting by TX and RX if a wrong connection occurs 

=>Answer: UART no SWAP function, you can check the UART pin, TX and RX is not shared, so, you need to make sure HW connection is correct.

Wish it helps you!
