Status
10. RDY will fall when the device is fully operational when coming out of sleep mode.
8. BP/UP can be changed coincident CONV falling. BP/UP must remain stable until RDY falls.
9. If CONV is held low continuously, conversions occur every 1600 MCLK cycles.
RDY
If RDY is tied to CONV, conversions will occur every 1602 MCLKs.
If CONV is operated asynchronously to MCLK, a conversion may take up to 1604 MCLKs.
RDY falls at the end of conversion.
SLEEP low to low-power state
SLEEP high to device active (Note 10)
