Hi,
attached the schematic, now found 32K768 crystal does not work when HIB_REG_ON_IN is low ,
while HIB_REG_ON_IN is high,the 32K768 crystal starts to work, so the 32K768 sleep clock seems to be forever after HIB_REG_ON_IN goes to high.
so it cannot meet the requirement of CYW43907 power up timming as attached(captured from 43907 datasheet).
pls advice,thanks.
