For TE input conversion, TV9 to TV0 = 0011111111 corresponds to approximately +1V
and TV9 to TV0 = 1100000000 to –1V respectively. (when the supply voltage = 5V)
For FE input conversion, FB9 to FB1 = 011111111 corresponds to approximately +1V
and FB9 to FB1 = 100000000 to –1V respectively. (when the supply voltage = 5V)

When using the FBIAS register in counter mode, counter operation stops when the
value of FB9 to 1 matches with FBL9 to 1.
