You need to set the option byte OPT2 = 0x02 (NOPT2 = 0xFD) to enable TIM2 CC3 and disable TIM3 CC1, following is the asm file to add in your project :
;This file contains the values to program in the option bytes.
;You can change the values below according to the device datasheet.
;Be careful to respect the complement bytes,
; or the default values of the option bytes will be used.
;See the device datasheet for more information on the meaning of each bit.
