and TMR1 interrupts
NMI, IRQ15 to IRQ0, KIN9 to KIN0, and WUE15 to WUE8 interrupts
When a transition is made between modes by means of an interrupt, the transition cannot be made
on interrupt source generation alone. Ensure that interrupt handling is performed after accepting the
interrupt request.
Always select high-speed mode before making a transition to watch mode or sub-active mode.
