Bands Select Change Timing and Valid Output
Whenever band selection BSEL pin input is changed, allow for band selection changeover to complete and stabilize. The output is valid only
after the second complete operating ‘awake’ phase after the band selection change is complete. Time taken for the output to be valid, after the
BSEL change, depends on timing of BSEL change during the sleep and awake phase; this time is up to 100ms typical and 200.1ms maximum
(TBC).
