8.2.3
When generate software interrupt is chosen, the CCP1
pin is not affected. Only an ECCP interrupt is generated
(if enabled).
8.2.4
In this mode, an internal hardware trigger is generated,
which may be used to initiate an action.
The special event trigger output of ECCP resets the
TMR1 register pair. This allows the CCPR1 register to
effectively be a 16-bit programmable period register for
Timer1.
The special event trigger output of ECCP module will
also start an A/D conversion if the A/D module is
enabled.

x = unknown, u = unchanged, - = unimplemented read as ’0’. Shaded cells are not used by Capture and Timer1.
The special event trigger will not set the
interrupt flag bit TMR1IF (PIR1<0>).
