typedef errnum_t(* r_ospl_callback_t)(const r_ospl_interrupt_t *InterruptSource, const r_ospl_caller_t *Caller)

The function type of interrupt callback.

Parameters:

InterruptSource	Source of interrupt
Caller	Driver's internal parameters about interrupt operations

Returns:: Error code. If there is no error, the return value is 0. The value set to "r_ospl_async_t::ReturnValue"

Description: This is type of the interrupt callback function running in the interrupt context and called from the interrupt handler.

It is possible to replace to application defined interrupt callback function by setting to "r_ospl_async_t::InterruptCallback". But it is usually not necessary to replace.

As interrupt callback function, the default interrupt callback function provided from the driver is used. It is unusual to use application defined interrupt callback function. Write the response code of the interrupt (event driven code) next to the code calling R_OSPL_EVENT_Wait function

Whether the asynchronous operation was ended is possible to know whether the variable of "r_ospl_async_state_t" type referred from R_DRIVER_GetAsyncStatus function is set to R_OSPL_RUNNABLE value.

It is not necessary to write the code of interrupt return (IRET) in the interrupt callback function. The interrupt handlers calling interrupt callback function calls IRET, if necessary.

It is not possible to divide interrupt callback functions by the kind of interrupt. Alternatively, it is possible to write operations in interrupt handlers calling interrupt callback function in porting layer under the driver. There are interrupt handlers by each interrupt numbers.

It is possible to signal any event from application defined interrupt
