2 PreScaleLED1
LED 1 PWM prescaler
PWM prescaler register for LED 1 (20 mA). Reduces
the 50 MHz input clock frequency to 5.55 MHz.
5.55 MHz/256 (8-bit resolution) = Approx. 20 kHz
PWM frequency. (Default =0x0009)
0x0018
40E2 0x9xxA
SUB 02
2 PreScaleLED2
LED 2 PWM prescaler
PWM prescaler register for LED 2 (350 mA). Reduces
the 50 MHz input clock frequency to 900kHz. 900 kHz/
256 (8-bit resolution) = Approx. 3.5 kHz PWM
frequency. (Default =0x0037)
