Dear bala_jss,

Rev A is an engineering early Sample with some limitations, You can order the production sample for your application instead. :-?

Are the (duty cycles of the) 4 PWM channels independent ?

When I try to set CCR(TIM4, CH4) to a value greater than CCR(TIM4, CH3) both (duty cycles) seems to latch to (TIM4, CH4). Am I missing something ? Any help is greatly appreciated.

I am using TIM4 in PWM1 Mode (TIM4CLK = 72 MHz, Prescaler = 17, TIM4 counter clock = 4 MHz, ARR = 1000 =>TIM4 Frequency = 4 KHz) on a STM32F103 Rev A.
