Shutdown Sequence
Enter:
Write 0x40 to register 0x05.
Wait at least 1 ms + 1.3 × t
stop
(where t
stop
is specified by register 0x1A).
If desired, reconfigure by returning to step 4 of initialization sequence.
Exit:
Write 0x00 to register 0x05 (exit shutdown command can not be serviced for as much as 240 ms after trim following AVDD/DVDD power-up ramp).
Wait at least 1 ms + 1.3 × t
start
(where t
start
is specified by register 0x1A).
Proceed with normal operation.
