windriver函数ReadWriteBlock是不是对pci突发读写访问？

请问windriver生成的驱动程序框架里面的函数WDC_DIAG_ReadWriteBlock是不是对pci突发读写访问？谢谢！

WDC_DIAG_ReadWriteBlock函数里面调用函数WDC_ReadAddrBlock，WDC_WriteAddrBlock，这两个函数的参数options可以取3个值：WDC_ADDR_RW_DEFAULT = 0x0,
/* Default: memory resource - direct access; autoincrement on block transfers */
WDC_ADDR_RW_INDIRECT = 0x2,
/* Memory resource only: use WD_Transfer() instead of direct memory access */
WDC_ADDR_RW_NO_AUTOINC = 0x4
/* Hold device address constant while reading/writing a block */
请问哪个是支持突发读写的？谢谢!!
