IPAC Interrupt Status Registers
Two interrupt indications can be read directly from the ISTA register and another six
interrupt indications from separate interrupt status registers and extended interrupt
registers for the B-channels (ISTAB, EXIRB, each for B-Channel A and B) and the D-
channel (ISTAD, EXIRD).
Each interrupt source can individually be disabled by setting the corresponding mask bit
in the interrupt mask register.
An overview of the interrupt sources is given below, a detailed description of the interrupt
structure is provided in chapter 3.3.
