Description
ADCINT2/CS2-ALARM = 1 when the ADC reading of internal
channel 2 (closed-loop) or the measurement of current sense 2
(open-loop) is out of range defined by the alarm threshold
registers.
ADCINT1/CS1-ALARM = 1 when the ADC reading of internal
channel 1 (closed-loop) or the measurement of current sense 1
(open-loop) is out of range defined by the alarm threshold
registers.

Description
Global data available flag.
ADC is ready (waiting) to be triggered. At power-up, will remain
not ready (0) until the ADC is powered up and at least one
channel is selected. If there is any write that would stop the ADC
including AMC Configuration 0, ADC MUX, or ADC alarm
threshold register writes, this bit also returns to not ready until
the device completes processing of these changes/updates,
after which time the ADC is ready to trigger again.
Goes to 0 when the ADC is triggered and is running. This bit
returns to 1 once the ADC is stopped.
Local temperature sensor data available flag for direct-mode
conversion.
Remote temperature sensor 2 data available flag for direct-mode
conversion.
Remote temperature sensor 1 data available flag for direct-mode
conversion.
ADCINT data available flag for direct-mode conversion.
ADCEXT data available flag for direct-mode conversion.
Current sense data available flags for direct-mode conversion.
Reserved for factory use
Status of SLEEP2 pin.
Status of SLEEP1 pin.
Status of PA_ON pin.
If equal to 0 the PA_ON pin is in the OFF state (PAVDD). If
equal to 1 the PA_ON pin is in the ON state (AGND).
Global alarm bit.
This bit is the OR function or all individual alarm bits of the
status register. This bit is set to 1 when any alarm condition
occurs and remains set until the status register is read. This bit
is cleared after reading the Alarm Status register.
