Figure 90. Read Sectors command (20h/21h)

The Read Sectors command reads one or more sectors of data from disk media and then transfers the
data from the device to the host.

The sectors are transferred through the Data Register 16 bits at a time. If an uncorrectable error occurs
the read will be terminated at the failing sector.

Output Parameters To The Device

Sector Count

The number of continuous sectors to be transferred. If zero is specified, then
256 sectors will be transferred.

Sector Number

This is the sector number of the first sector to be transferred. (L = 0)

In LBA mode this register contains the LBA bits 0–7. (L = 1)

Cylinder High/Low

This is the cylinder number of the first sector to be transferred. (L = 0)

In LBA mode this register contains the LBA bits 8–15 (Low) and bits
16–23 (High). (L = 1)

This is the head number of the first sector to be transferred. (L = 0)

In LBA mode this register contains the LBA bits 24–27. (L = 1)

This is the retry bit. If is set to one and then retries are disabled.
