#include <nitro/card.h>
static inline void CARD_ReadFlashAsync( u32 src, void *dst, u32 len, MIDmaCallback callback, void *arg);
src | The FLASH address of the transfer source |
dst | Transfer destination memory address |
len | Byte length of data being read |
callback | Callback function for when the process completes. If the callback is not necessary, specify NULL. This callback is called from inside the interrupt handler. |
arg | Argument passed to the callback function when the process completes. If NULL has been specified for the callback, this value is simply ignored. |
None.
This function asynchronously loads data from the FLASH device. This function immediately returns control. In order to use this function, you must first lock the access bus with the CARD_LockBackup
function.
To wait for the process to end, use the CARD_WaitBackupAsync
function. To determine the result of the process, call the CARD_GetResultCode
function after the process has ended.
This function communicates with the ARM7 processor internally via PXI.
The process will not end if PXI interrupts are not enabled.
This function executes an asynchronous process using an internal thread. To learn more about this internal thread, see the explanation for the CARD_GetThreadPriority
function.
