(1) R = read, W = write
(2) Default value
(3) Requires 500 μs maximum for the oscillator to be up and running once OSC 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.
NOTE
The OSC bit (Bit 4) must be set to 0 before any outputs will turn on. Proper operation
requires this bit to be 0. Setting the bit to a 1 will turn all channels off.
