When Low RPM standby mode is the deepest Power Saving mode and the value in Sector Count register is
between 01h and 3Fh,
between 01h and 3Fh,

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.
