客户在使用S6J342AHTBSV20000时,发现刚开机时RTC计时是准确的,在芯片进入睡眠(睡眠模式是从shutdown进入的Standby mode)之后唤醒RTC计时就变快了,请问一下有哪些因素会导致这样的现象?

1. Which clock was used in PSS mode (both timer shutdown mode and standby mode)?

2. Are you using PWU mode (patial wakeup mode)?

3. If you can reproduce the issue on Cypress S6J3400 EVB?

4. Please kindly provide the measured RTC data before and after low power mode.

Best regards,
