time depends on the PWM frequency. For example, if the PWM frequency is 244 Hz,
then the delay value has a resolution of 4 ms. If the PWM frequency is 488 Hz, then the
delay time resolution is 2 ms. This factor is a great help in simplifying dynamic turning-
indicator sequences.
The microcontroller has the possibility of reading back the current PWM values in every
cycle. These values are accessible from the register 42h to 59h, as shown in Table 6.
This accessibility ensures maximum control of the system and LED board feedback.
