When D15 = D14 = D13 = D12 = 1. ($34F)
D11 = 0, D10 = 1
FBIAS register write
FB9 to FB1: Data; FB9 is MSB two's complement data.
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 D15 = D14 = D13 = D12 = D11 = 1 ($34F)
D10 = 0
FBIAS LIMIT register write
FBL9 to FBL1: Data; data compared with FB9 to 1, FBL9 = MSB.
When using the FBIAS register in counter mode, counter operation stops when the
value of FB9 to 1 matches with FBL9 to 1.

When D15 = D14 = D13 = D12 = 1. ($34F)

TRVSC register write
TV9 to TV0: Data; TV9 is MSB two's complement data.
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)
Note)
When the TRVSC register is read out, the data length is 9 bits. At this time, data corresponding to
each bit of TV8 to TV0 during external write are read out.
When reading out internally measured values and then writing these values externally, set TV9 the
same as TV8.
