CARD_WriteEepromAsync


C Specification

#include <nitro/card.h>

static inline void CARD_WriteEepromAsync( 
    u32              dst, 
    const void      *src, 
    u32              len, 
    MIDmaCallback    callback, 
    void             *arg);
    

Description

Writes data asynchronously to an EEPROM device.

Before using this function, you must lock the access bus using the CARD_LockBackup function.

Use the CARD_WaitBackupAsync function to wait for the process to complete. To determine the result when complete, call the CARD_GetResultCode function.

This function returns control promptly.

This function performs communications internally with the I/O processor through PXI. Be aware that the process will not complete if the PXI interrupt is not valid.

Internal Operation

This function uses an internal thread to process data asynchronously. See the description of the CARD_GetThreadPriority function for information about this thread.

Arguments

dst Transfer destination EEPROM address
src Transfer source memory address
len Length of write data (in bytes)
callback Callback function upon completion.
Specify NULL when not needed.
arg Argument passed to callback function upon completion.
Ignored when the callback specifies NULL.

Return Values

None.
