Figure 80. Enable/Disable Delayed Write command (FAh)

The Enable/Disable Delayed Write command sets if the Delayed Write function is enabled or disabled.
Delayed Write function is enabled or disabled according to the feature register's value.

Even if the Delayed Write function is enabled by this command, Delayed Write does not work when the
Write Cache function is disabled.

For details for this function, refer to Section 11.13, "Delayed Write function (vendor specific)" on
page 100.

Output Parameters To The Device
