Power-down modes
A transition between different modes cannot be made to occur simply because an interrupt
request is generated. Make sure that interrupt handling is performed after the interrupt is
accepted.
Details on the mode transition conditions are given in the explanations of each mode,
in sections 5.2 to 5.9.
