General Description
The TPS65920/TPS65930 device provides the MADC resource to the host processors in the system
(hardware and software conversion modes).
The MADC generates interrupt signals to the host processors. Interrupts are handled primarily by the
MADC internal secondary interrupt handler and secondly at the upper level (outside the MADC) by the
TPS65920/TPS65930 interrupt primary handler.
