Description
DAC4-HIGH-ALARM = 1 when DAC4 has exceeded the upper
output limit set by DAC34-UP-THRESH[11:0].
DAC3-HIGH-ALARM = 1 when DAC3 has exceeded the upper
output limit set by DAC34-UP-THRESH[11:0].
DAC2-HIGH-ALARM = 1 when DAC2 has exceeded the upper
output limit set by DAC12–UP-THRESH[11:0].
DAC1-HIGH-ALARM = 1 when DAC1 has exceeded the upper
output limit set by DAC12–UP-THRESH[11:0].
Reserved for factory use.
AVSS_ALARM = 1 when AV_SS is out of range.
RT2-HIGH-ALARM = 1 when remote temperature sensor 2 is
out of the range defined by the upper threshold.
Always zero when the remote sensor is disabled.
RT2-LOW-ALARM = 1 when remote temperature sensor 2 is out
of the range defined by the lower threshold.
Always zero when the remote sensor is disabled.
RT1-HIGH-ALARM = 1 when remote temperature sensor 1 is
out of the range defined by the upper threshold.
Always zero when the remote sensor is disabled.
RT1-LOW-ALARM = 1 when remote temperature sensor 1 is out
of the range defined by the lower threshold.
Always zero when the remote sensor is disabled.
LT-HIGH-ALARM = 1 when the local temperature sensor is out
of the range defined by the upper threshold.
Always zero when the on-chip sensor is disabled.
LT-LOW-ALARM = 1 when the local temperature sensor is out
of the range defined by the lower threshold.
Always zero when the on-chip sensor is disabled.
ADCINT4/CS4-ALARM = 1 when the ADC reading of internal
channel 4 (closed-loop) or the measurement of current sense 4
(open-loop) is out of range defined by the alarm threshold
registers.
ADCINT3/CS3-ALARM = 1 when the ADC reading of internal
channel 3 (closed-loop) or the measurement of current sense 3
(open-loop) is out of range defined by the alarm threshold
registers.
