Note 1.
When Feature register is 03h (=Set Transfer mode), the Sector Count Register specifies the transfer
mechanism. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value.

Note 2.
If the number of auto reassigned sectors reaches the device’s reassignment capacity, the write cache
function will be automatically disabled. Although the device still accepts the Set Features command (with
Feature register = 02h) without error, the write cache function will remain disabled. For current write
cache function status, please refer to the Identify Device Information(129word) by Identify Device
command. Power off must not be done in 5 seconds after write command completion when write cache
is enabled.
Note 3.
When the Feature register is set to 10h or 90h, the value set to the Sector Count register specifies the
specific Serial ATA feature to enable or disable.
