End of interrupt (EOI) is a feature used for software handshake with pulsed interrupts.
EOI MMR functionality is provided for EVE-generated interrupts that are mapped as outputs to the system. This feature is necessary when the external system uses the pulsed version of a given interrupt. Because all interrupts inside EVE are level interrupts, the EOI feature is not required for those interrupts.
The EVE subsystem does not condition interrupts for internal submodules (EDMA, interconnect, MMU, or SCTM). Those interrupts are mapped directly as outputs to the system and no EOI functionality is provided for them.
Table 8-20 lists the EOI mapping for the required interrupts.
EVE MMR Value | EVE Interrupt Overview |

2 | eve_int1_out |
3 | eve_int2_out |
4 | eve_int3_out |
