This command returns the native maximum address. The native maximum address is the highest
address accepted by the device in the factory default condition. The native maximum address is the
maximum address that is valid when using the Set-Max-Address command.
The Read-Native-Max-Address command output will take the following format:

Sector Count
Feature (1)
X
This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of
0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When
this command is issued and after each sector of data (except the last one) has been read by the host,
the ATA Flash Disk Controller sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and
generates an interrupt. The host then reads the 512 Bytes of data from the buffer.
