15.14.1 MIOS Interrupt Request Submodule (MIRSM)
MPC555
USER’S MANUAL
The MIOS interrupt request submodule gathers service request flags from each group
of up to 16 submodules and transfers those requests to the MIOS1 interrupt control
section (ICS).
Each submodule that is capable of generating an interrupt can assert a flag line when
an event occurs. In the MIOS1 configuration, there are eighteen flag lines and two
MIRSMs are needed.
• The MIOS interrupt request submodules (MIRSM).
