Analog Input Select. This four-bit field determines which of the following analog inputs are sampled
during this time slot. All other values are reserved. By default, this register is set to 0110.
0000 = V0P - VN
0001 = V1P - VN
0010 = V2P - VN
0011 = I0P - I0N
0100 = I1P - I1N
0101 = I2P - I2N
0110 = INP - VN
1xxx = Temperature
