RO 0x0000.0000 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Conversion Rate
This field specifies the relative sample rate of the ADC and is used in
run, sleep, and deep-sleep modes. It allows the application to reduce
the rate at which conversions are generated relative to the maximum
conversion rate.
Value Description
0x0
Reserved
0x1
Eighth conversion rate. After a conversion completes, the
logic pauses for 112 T_ADC periods before starting the next
conversion.
0x2
Reserved
0x3
Quarter conversion rate. After a conversion completes, the
logic pauses for 48 T_ADC periods before starting the next
conversion.
0x4
Reserved
0x5
Half conversion rate. After a conversion completes, the logic
pauses for 16 T_ADC periods before starting the next
conversion.
0x6
Reserved
0x7
Full conversion rate (F_CONV) as defined by T_ADC and N_SH.
