When Low RPM standby mode is the deepest Power Saving mode and the value in Sector Count register is
between 01h and 3Fh,
120<=
Y
1
<=435 [sec] (default: 120 [sec])
Y

=600 [sec]
where
x
is the value in Sector Count register,
y
1
is the idle time to Low Power Idle mode, and
y
2
is the idle time
to Low RPM standby mode.
If Low power idle mode has already been enabled (i.e.,
y
1
has been set) before Low RPM standby mode is
enabled,
y
1
is preserved. If Low power idle mode is disabled (i.e.,
y
1
has not been set yet),
y
1
becomes 120[sec]
when Low RPM standby mode is enabled.
