WebOct 29, 2010 · When I start Timer2 by doing T2CON[TMR2ON]=1, than I can see: 1) TMR2 register chaning 2) All changes done manually to CCPR2L got automatically copied to CCPR2H (latched, I guess). It does not copy when TMR2ON=0. Which means, CCP module is finally active on RB3 pin. No PWM, still.
