For the on-chip oscillator overflow periods, see section
21, Electrical Characteristics.
In active (medium-speed), sleep (medium-speed),
subactive, and subsleep modes, the 00xx value and the
interval timer mode cannot be set simultaneously.
In subactive and subsleep modes, when the subclock
frequency is φ
mode cannot be set simultaneously.
