4.2.3
The next table shows the bit assignments for the interrupt information long word.
When an interrupt occurs MUNICH32 sets the INT bit and writes the interrupt information
and the channel number into the interrupt circular buffer. At the same time it generates
an interrupt pulse. The classes of error (for example host initiated interrupt or CRC error)
of a channel in one direction are treated independently of each other. If several interrupt
events coincide they will be indicated to the host with one shared interrupt.
Bit assignment for interrupt queue
There are 3 classes of bits in the interrupt:
1. Bits present in each interrupt:
