|
|
* @brief Initialize the IPC ISR feature, must be called for each CPU
|
|
*
|
|
* @note This function is called from ipc_task().
|
|
*
|
|
* This function initializes the IPC ISR feature and must be called before any other esp_ipc_isr...() functions.
|
|
* The IPC ISR feature allows for callbacks (written in assembly) to be run on a particular CPU in the context of a
|
|
* High Priority Interrupt.
|
|
*
|
|
* - This function will register a High Priority Interrupt for a CPU where it is called. The priority of the interrupts is dependent on
|
|
* the CONFIG_ESP_SYSTEM_CHECK_INT_LEVEL option.
|
|
* - Callbacks written in assembly can then run in context of the registered High Priority Interrupts
|
|
* - Callbacks can be executed by calling esp_ipc_isr_call() or esp_ipc_isr_call_blocking()
