Description
This register contains the eight MSBs of the 10-bit t
Description
Reserved.
These bits contain the two LSBs of the 10-bit t
Register 0xFE0C, which contains the eight MSBs of the t
1 = PWM modulation acts on the t
0 = no PWM modulation of the t
1 = positive sign. Increase of PWM modulation moves t
0 = negative sign. Increase of PWM modulation moves t
