Other Parts Discussed in Thread: DRA821

Hi expert.

Take MCU_MCAN0 and MCAN0 as example, May I ask your great help to check if customer still need another IO to act as wakeup IO?

And may I ask your help to check the same question for UART (simulate LIN), take example MCU_UART0 and UART1?

thank you!

Pin A17, C16 - Yes both these pins support IO Retention/Wkup mode in the MCU domain. No additional pins are required for wake-up.

Pin V20, T18 - Yes both of these pins support IO retention/Wkup mode in the MAIN domain. No additional pins are required for wake-up.
