RST Module
Functional
NRST release doesn't get detected when LFCLK_IN is LFCLK source and LFCLK_IN gets disabled
When LFCLK = LFCLK_IN and we disable the LFCLK_IN, then comes a corner scenario where NRST pulse edge detection is missed and the device doesn't come out of reset. This issue is seen if the NRST pulse width is below 608us. NRST pulse above 608us, the reset can appear normally.
Keep the NRST pulse width higher than 608us to avoid this issue.
