(1) R = read, W = write
(2) Default value
(3) Requires 500 µs maximum for the oscillator to be up and running once SLEEP bit has been set to logic 1. Timings on LED outputs are
not ensured if PWMx, GRPPWM, or GRPFREQ registers are accessed within the 500-µs window.
(4) No blinking or dimming is possible when the oscillator is off.
