Part Number: PROCESSOR-SDK-AM62X

SDK:9.1

When using the main domain gpio interrupt, after waking up from sleep, the main domain gpio interrupt cannot enter the interrupt function to handle the interrupt.

The GPIOs used are GPIO1-31 and GPIO0_12, respectively.

Before going to sleep, read the GPIO interrupt status register (GPIO0-INTSTAT01 Register), and the result is shown in the following figure

After waking up from sleep, read the GPIO interrupt status register, and the result is shown in the following figure

And the GPIO interrupt status register value cannot be manually cleared. This issue has been validated on SDK9.1 and EVK boards and can be reproduced
