[RTC] RTC Register Read Error After Wake-up from Light-sleep Mode

Affected revisions: v0.0 v0.1 v0.2

Description

If an RTC peripheral is turned off in Light-sleep mode, there is a certain probability that after waking up from Light-sleep, the CPU of ESP32-S3 will read the registers in the RTC power domain incorrectly.

Workarounds

Users are suggested not to power down RTC peripherals in Light-sleep mode. There will be no impact on power consumption.

This issue has been bypassed in ESP-IDF v4.4 and above.

Solution

No fix scheduled.
