In addition to the expanded range of modes available
through the CCPxCON and ECCPxAS registers, the
ECCP modules have two additional registers associated
with Enhanced PWM operation and auto-shutdown
features. They are:
• ECCPxDEL (Enhanced PWM Control)
• PSTRxCON (Pulse Steering Control)
17.1
The Enhanced CCP module may have up to four PWM
outputs, depending on the selected operating mode.
These outputs, designated PxA through PxD, are
routed through the Peripheral Pin Select (PPS)
module. Therefore, individual functions may be
mapped to any of the remappable I/O pins, RPn. The
outputs that are active depend on the ECCP operating
mode selected. The pin assignments are summarized
in Table 17-4.
To configure the I/O pins as PWM outputs, the proper
PWM mode must be selected by setting the PxM<1:0>
and CCPxM<3:0> bits. The appropriate TRIS direction
bits for the port pins must also be set as outputs and the
output functions need to be assigned to I/O pins in the
PPS module. (For details on configuring the module,
see Section 9.7 “Peripheral Pin Select (PPS)”.)

ECCP Outputs and Configuration
PIC18F46J50 FAMILY
17.1.1
The ECCP modules utilize Timers 1, 2, 3 or 4, depending
on the mode selected. Timer1 and Timer3 are available
to modules in Capture or Compare modes, while Timer2
and Timer4 are available for modules in PWM mode.
TABLE 17-1:
The assignment of a particular timer to a module is
determined by the Timer-to-ECCP enable bits in the
TCLKCON register (Register 12-3). The interactions
between the two modules are depicted in Figure 17-1.
Capture operations are designed to be used when the
timer is configured for Synchronous Counter mode.
Capture operations may not work as expected if the
associated timer is configured for Asynchronous Counter
mode.
