# PSRAM MSPI Interrupt Handling
|
|
|
|
## Overview
|
|
|
|
This file (`system_layer/esp_psram_mspi.c`) handles PSRAM-specific MSPI interrupt registration.
|
|
|
|
| Chip Type | `MSPI_LL_INTR_SHARED` | Behavior |
|
|
|--------------|-----------------------|------------------------------------------------------|
|
|
| Shared IRQ | 1 | Register to shared MSPI dispatcher |
|
|
| Separate IRQ | 0 | Register standalone PSRAM ISR via `esp_intr_alloc()` |
|
|
|
