Description

This function synchronously reads out data from the FLASH device. The function does not return control until it has finished processing. It returns TRUE if the process was successful or FALSE if it failed. To get the detailed result value when the process fails, call the CARD_GetResultCode function. In order to use this function, you must first lock the access bus with the CARD_LockBackup function.

This function communicates with the ARM7 processor internally via PXI.
The process will not end if PXI interrupts are not enabled.
