I am working on STM8S (STM8S003F3) MCU . This is 20 bit MCU. I So i am using 2 timers TIMER1 CHANNEL2 (on pin no. PC7 ) and TIMER2 CHANNEL1 (on pin no. PD4) and i select ARF0 OPTION BYTE for TIMER1 CHANNEL2 then TIMER2 CHANNEL1 (on pin no. PD4) does not work , but both are separately working . so now what is problem occur when we use both at a time .
