Other Parts Discussed in Thread: USB2ANY
I have been facing an issue with the use of the LMK04610.
According to the datasheet of the LMK04610, RESETN should be toggled after power-up before configuring SPI registers (paragraph 9.5.1 in the datasheet). There is no delay between RESETN release and the beginning of SPI programming in the datasheet but I have read in some posts that no delay is necessary: SPI can be used right after the release of RESETN.
We use one LMK04610 on a specific board and we made the following observation: when we toggle the RESETN and try to program SPI registers afterwards, the registers configuration do not change as if the write into registers were not taken into account. But when we try to program registers without toggling RESETN we are able to configure registers.
It is surprising because toggling RESETN before SPI programming should work.
Could you provide us some support please ?
