In the CC110L datasheet chapter 5.5 is written.
When CSn is pulled low, the MCU must wait until CC110L SO pin goes low before starting to transfer the
header byte. This indicates that the crystal is running. Unless the chip was in the SLEEP or XOFF states,
the SO pin will always go low immediately after taking CSn low.
Is possible to know how many time is "immediately"?
Many thanks in advance.
