BIT 7
MODTC: Modulation TempCo
0 = Positive TempCo. For a TINDEX (Table 02h, Register 81h) below the MODTI value (Table 02h,
Register C2h), the 8-bit recalled value from the MODULATION LUT is stored in the lower 8 bits of the
MODULATION register. For a TINDEX greater than or equal to MODTI, the recalled value is stored in the
upper 8 bits of the MODULATION register.
1 = Negative TempCo. For a TINDEX below the MODTI value, the 8-bit recalled value from the
MODULATION LUT is stored in the upper 8 bits of the MODULATION register. For a TINDEX greater
than or equal to MODTI, the recalled value is stored in the lower 8 bits of the MODULATION register.
BIT 6
DAC1TC: DAC1 TempCo
0 = Positive TempCo. For a TINDEX (Table 02h, Register 81h) below the DAC1TI value (Table 02h,
Register C3h), the 8-bit recalled value from the DAC1 LUT is stored in the lower 8 bits of the DAC1
DAC’s register. For a TINDEX greater than or equal to DAC1TI, the recalled value is stored in the upper
8 bits of the DAC1 DAC’s register.
1 = Negative TempCo. For a TINDEX below the DAC1TI value, the 8-bit recalled value from the DAC1
LUT is stored in the upper 8 bits of the DAC1 DAC’s register. For a TINDEX greater than or equal to
DAC1TI, the recalled value is stored in the lower 8 bits of the DAC1 DAC’s register.
BIT 5
DAC2TC: DAC2 TempCo
0 = Positive TempCo. For a TINDEX (Table 02h, Register 81h) below the DAC2TI value (Table 02h,
Register C4h), the 8-bit recalled value from the DAC2 LUT is stored in the lower 8 bits of the DAC2
DAC’s register. For a TINDEX greater than or equal to DAC2TI, the recalled value is stored in the upper
8 bits of the DAC2 DAC’s register.
1 = Negative TempCo. For a TINDEX below the DAC2TI value, the 8-bit recalled value from the DAC2
LUT is stored in the upper 8 bits of the DAC2 DAC’s register. For a TINDEX greater than or equal to
DAC2TI, the recalled value is stored in the lower 8 bits of the DAC2 DAC’s register.
