Stop Mode Select. Setting this bit halts the oscillator and blocks external clocks. This bit always reads as a 0.
All digital pins and DACs keep their respective output values. Internal REF dies. Exit with RESET.
Idle Mode Select. Setting this bit freezes the CPU, Timer 0, 1, and 2, and the USARTs; other peripherals remain
active. This bit will always be read as a 0. All digital pins and DACs keep their respective output values. Internal REF
remains unchanged. Exit with AI (A6h) and EWU (C6h) interrupts.
