Conversion Rate
R/W
These four bits set the conversion rate of the ADM1033. Changing these bits does not
update the conversion rate until the start of the next round robin.
0000 = 0.0625 conversions/second
0001 = 0.125 conversions/second
0010 = 0.25 conversions/second
0011 = 0.5 conversions/second
0100 = 1 conversion/second
0110 = 4 conversions/second
0111 = 8 conversions/second = Default
1000 = 16 conversions/second
1001 = 32 conversions/second
1010 = 64 conversions/second
