UFCauseInter
Parameter
HSCSTS.UFCauseInter
The Underflow Interrupt status bit sets (1) when the HSC accumulator counts
through the underflow value and the HSC interrupt is triggered. This bit can be
used in the control program to identify that the underflow condition caused the
HSC interrupt. If the control program needs to perform any specific control
action based on the underflow, this bit is used as conditional logic.
This bit can be cleared (0) by the control program and is also cleared by the HSC
sub-system whenever these conditions are detected:
•
Low Preset Interrupt occurs
•
High Preset Interrupt occurs
•
Overflow Interrupt occurs
HPCauseInter
Parameter
HSCSTS.HPCauseInter
The High Preset Interrupt status bit sets (1) when the HSC accumulator reaches
the high preset value and the HSC interrupt is triggered. This bit can be used in
the control program to identify that the high preset condition caused the HSC
interrupt. If the control program needs to perform any specific control action
based on the high preset, this bit is used as conditional logic.
This bit can be cleared (0) by the control program and is also cleared by the HSC
sub-system whenever these conditions are detected:
•
Low Preset Interrupt occurs
•
Underflow Interrupt occurs
•
Overflow Interrupt occurs
