6.11 LFXT_ERR_01

LFXT Module

Category

Functional

Function

LFXT clock is not getting active until writing something into LFCLKCFG mmr

Description

After setting the STARTLFXT, the CLKSTATUS is updating as expected, but LFXT clock is not seen on LFCLK_OUT until a write into the LFCLKCFG is made. And if LFXT is configured as a source to LFCLK tree, VBAT supply goes down and comes up back again, in that case the LFCLK is blank until a write into LFCLKCFG is made.

Workaround

Manually configuring LFCLKCFG register (such as XT1DRIVE field) to make LFXT valid, every time LFXT starts from blanking state.
