Figure 107. Write Long Command (32h/33h)

The Write Long command transfers the data and the ECC bytes of the designated one sector from the

host to the device, then the data and the ECC bytes are written to the disk media.

After 512 bytes of data have been transferred, the device will keep setting DRQ=1 to indicate that the

device is ready to receive the ECC bytes from the host. The data is transferred 16 bits at a time, and the

ECC bytes are transferred 8 bits at a time. The number of ECC bytes are 4 or 40 according to setting of

Set Feature option. The default number after power on is 4 bytes.

The retry bit. If set to one, then retries are disabled.R
