1. Out of the 16 settings, PWM Width (PW) can select only one of 1, 2, 4, or 8 (not a 4-bit mixture)

2. When using a 2N Track or an M Track, more than 512 Tracks is not recommended (potential for error within the algorithm)

3. There can be a 1~2 error in the PWM Duty (PD), so set to fixed value + 2
