Table 26. AUTO-DAC-CLR-SOURCE Register BIT NAME DEFAULT R/W DESCRIPTION 15 — 0 R Reserved. Writing to this bit causes no change. Reading this bit returns '0'. CH0 alarm clear bit. 0 = CH1-ALR goes to '1' and does not force any DAC to a clear status 14 CH0-ALR-CLR 0 R/W 1 = DAC-n is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the CH0-ALR bit in the status register are set ('1') CH1 alarm clear bit. 0 = CH1-ALR goes to '1' and does not force any DAC to a clear status 13 CH1-ALR-CLR 0 R/W 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the CH1-ALR bit in the status register are set ('1') CH2 alarm clear bit. 0 = CH2-ALR goes to '1' and does not force any DAC to a clear status 12 CH2-ALR-CLR 0 R/W 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the CH2-ALR bit in the status register are set ('1') CH3 alarm clear bit. 0 = CH3-ALR goes to '1' and does not force any DAC to a clear status 11 CH3-ALR-CLR 0 R/W 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the CH3-ALR bit in the status register are set ('1') Local temperature sensor low alarm clear bit. LT-Low-ALR- 0 = LT-Low-ALR goes to '1' and does not force any DAC to a clear status 10 0 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the LT-Low-ALR bit in the status register are set ('1') Local temperature sensor high alarm clear bit. LT-High-ALR- 0 = LT-High-ALR goes to '1' and does not force any DAC to a clear status 9 0 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the LT-High-ALR bit in the status register are set ('1') Remote temperature sensor D1 low alarm clear bit. D1-Low-ALR- 0 = D1-Low-ALR goes to '1' and does not force any DAC to a clear status 8 0 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the D1-Low-ALR bit in the status register are set ('1') Remote temperature sensor D1 high alarm clear bit. D1-High-ALR- 0 = D1-High-ALR goes to '1' and does not force any DAC to a clear status 7 0 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the D1-High-ALR bit in the status register are set ('1') Remote temperature sensor D2 low alarm clear bit. D2-Low-ALR- 0 = D2-Low-ALR goes to '1' and does not force any DAC to a clear status 6 0 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the D2-Low-ALR bit in the status register are set ('1') Remote temperature sensor D2 high alarm clear bit. D2-High-ALR- 0 = D2-High-ALR goes to '1' and does not force any DAC to a clear status 5 0 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the D2-High-ALR bit in the status register are set ('1') D1 fail alarm clear bit. 0 = D1-FAIL-ALR goes to '1' and does not force any DAC to a clear status 4 D1-FAIL-CLR 0 R/W 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the D2-FAIL-ALR bit in the status register are set ('1') D2 fail alarm clear bit. 0 = D2-FAIL-ALR goes to '1' and does not force any DAC to a clear status 3 D2-FAIL-CLR 0 R/W 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the D2-FAIL-ALR bit in the status register are set ('1') Thermal alarm clear bit. THERM-ALR- 0 = THERM-ALR goes to '1' and does not force any DAC to a clear status 2 1 R/W CLR 1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN register and the THERM-ALR bit in the status register are set ('1') 1 — 0 R Reserved. Writing to this bit causes no change. Reading this bit returns '0'. 0 — 0 R Reserved. Writing to this bit causes no change. Reading this bit returns '0'. 74 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: AMC7812B |
