LMK04906: LMK04906 register configuration

Hi team
     If I want to modify the value of the register after the PLL is locked, how do we write it? 
Need to write twice when input configuration? The example described in the specification is not very clear。

    Hi Harry,

    for some registers do need some extra SPI clock cycles to update to new values.

    So, you can either send more SPI clocks or resend the same register content again to take effect.

    regards,
