MODACT
Modulation Active Flag
The MODACT flag indicates that the channel is
enabled and active thus executing a modulation
cycle.
1 Channel is
active
0 Channel is not active
3
MAXL
ADC Maximum Limit Detection Flag
The MAXL flag indicates that the ADC result which TAG is addressing this channel achieved or
passed the maximum allowed limit specified in the ADCMAX register. This flag is set only if the
channel is in the
active state (see Section 23.1.2.3, Channel modes ).
1 ADC Maximum Limit Detected
0 Normal operation
4
OCDF
Open Circuit Detection Flag
The OCDF flag indicates that an open circuit was detected in the channel load using the PWM
monitored modulation, as described in
Section 23.6, “Monitored modulation . This Flag is set
only of the channel is in the active state.
1 Open Circuit Detected
0 Normal operation
5
SCDF
Short Circuit Detection Flag
The SCDF flag indicates that a short circuit was detected in the channel load using the PWM
monitored modulation, as described in
Section 23.6, “Monitored modulation . This Flag is set if
the channel activation window signal is set (eTPU channel or SWMC bit).
1 Short Circuit Detected
0 Normal Operation
