AUTO-DAC-CLR-SOURCE Register (Read or Write, Address = 53h, Default = 0004h)
This register selects which alarm forces the DAC into a clear state, regardless of which DAC operation mode is
active, auto, or manual.

DESCRIPTION
R Reserved. Writing to this bit causes no change. Reading this bit returns '0'.
CH0 alarm clear bit.
R/W
0 = CH1-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = CH1-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = CH2-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = CH3-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = LT-Low-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = LT-High-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = D1-Low-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = D1-High-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = D2-Low-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = D2-High-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = D1-FAIL-ALR goes to '1' and does not force any DAC to a clear status
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.
R/W
0 = D2-FAIL-ALR goes to '1' and does not force any DAC to a clear status
1 = DACn is forced to a clear status if both the ACLRn bit in the AUTO-DAC-CLR-EN
