(1) R = read, W = write
(2) Default value
(3) It takes 500 μs max. for the oscillator to be up and running once SLEEP bit has been set from logic 1 to 0. Timings on LEDn outputs are
not guaranteed if PWMx, GRPPWM, or GRPFREQ registers are accessed within the 500 μs window.
(4) No LED control (on, off, blinking, or dimming) is possible when the oscillator is off. Write to a register cannot be accepted during SLEEP
mode. When you change the LED condition, SLEEP bit must be set to logic 0.
