code error in clocktick init. (PIC18 port)

Hi, I found that in prvSetupTimerInterrupt()  OpenTimer1() is called with argument T1_CCP1_T3_CCP2. This argument implies setting of some T3CON bits to configure timer/ccp pairs, but OpenTimer1 doesn’t do that. Only OpenTimer3 can get that argument. On the other hand, accidental &T1_CCP1_T3_CCP2 with the other arguments could result in unexpected behaviour. Paul van der Hulst
