(45)WRITE DMA EXT (X’35’): Option (customizing)

•Description

This command is the extended command of the WRITE DMA command. The LBA specification is increased from 28 bits to 48 bits, and the maximum number of sectors that can be transferred by a single command is changed from 100h to 10000h. Other command controls are the same as those of the WRITE DMA command.
