Hello everyone:
I wanna emulate my program in MPlab by choosing MPLAB SIM as the debugger. However, I found that even the context in CCPR1L and CCPR1H met that in Timer 1, nothing happened. The CCP1IF did not be set at all. Did anyone met this problem before?

My init section as follow:

The timer1 was set as D8 00 at first
