Hi Tony,

Generally WKUP domain peripheral PINs have wakeup capability from low power modes.

Please elaborate your query to provide context, use case customer is looking for.

Thanks & Regards,

Sunita.

Sunita,

Customer just want to know if it is directly controlled by MPU A53, now I know WKUP peripheral is.

Are peripherals with prefix MCU_ also controllable from A53 directly, and Linux driver is ready?

Hi,

Yeah, you can control those. For simple example, you can see our UART diagnostic and find out that how MCU_UART and WKUP_UART are getting accessed by A53 and How MAIN_UART and WKUP_UART are getting accessed by MCU domain, C:\ti\pdk_am65xx_07_01_00_55\packages\ti\board\diag\uart.
