Address 0x05 (PWM1)

Bit #

76543210

Default value

10000000

PWM1 register determines the duty cycle of DIM1. The LED outputs are LOW (LED on) when the count is less than the value in PWM1 and HIGH (LED off) when

it is greater. If PWM1 is programmed with 0x00, LED output is always HIGH (LED off).

The duty cycle of DIM1 is: PWM1/256

Default value is 50% duty cycle.
