16.2
The Capture mode of the ECCP module is virtually
identical in operation to that of the standard CCP mod-
ule as discussed in Section 15.1 “CCP1 Module”.
The differences are in the registers and port pins
involved:
• The 16-bit Capture register is ECCPR1
• The capture event is selected by control bits
• The interrupt bits are ECCP1IE (PIE2<0>) and
• The capture input pin is RD4 and its corresponding
Other operational details, including timer selection,
output pin configuration and software interrupts, are
exactly the same as the standard CCP module.
16.2.1
The special capture event for the reception of CAN mes-
sages (Section 15.2.5 “CAN Message Time-Stamp”)
is not available with the ECCP module.

16.3
The Compare mode of the ECCP module is virtually
identical in operation to that of the standard CCP
module as discussed in Section 15.2 “Capture
Mode”. The differences are in the registers and port
pins as described in Section 16.2 “Capture Mode”.
All other details are exactly the same.
16.3.1
Except as noted below, the special event trigger output
of ECCP1 functions identically to that of the standard
CCP module. It may be used to start an A/D conversion
if the A/D module is enabled.
