9.3.6.1
The eight MSIRs indicate which of the up to 32 interrupt sources sharing the message register have
pending interrupts. These registers are cleared when read. A write to these registers has no effect.
Table 9-33
9.3.6.2
MSISR, shown in
bit is set when the corresponding MSIR has an active interrupt. The status bit is 0 if all the corresponding
shared interrupt sources are cleared for that MSIR.
