This page descriptor is used to set the time over which the power condition
state is transformed into the idle condition or standby condition state.
However, because the HDD does not support the above states, the parameter
cannot be set on this page.
a. Idle
Specifies whether to permit the HDD to enter the Idle condition when the
HDD does not receive a command within the time specified in the "Idle
Condition Timer" field.
The HDD disregards this setting and executes Power Save.
b. Idle Condition Timer
Specifies the time before the HDD enters the Idle condition. When the Idle
bit is "1", the HDD disregards the specified value and enters Power Save
mode in two seconds (x 14) fixed.
c. Standby (unsupported)
Specifies whether to permit the HDD to enter the Standby condition if the
HDD does not receive a command within the time specified in the "Standby
Condition Timer" field.
