PIC18F87K90 FAMILY
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
• ECCPxDEL – Enhanced PWM Control
• PSTRxCON – Pulse Steering Control
19.1
The Enhanced CCP module may have up to four PWM
outputs, depending on the selected operating mode.
The CCPxCON register is modified to allow control
over four PWM outputs: ECCPx/PxA, PxB, PxC and
PxD. Applications can use one, two or four of these
outputs.
The outputs that are active depend on the selected
ECCP operating mode. The pin assignments are
summarized in
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.
19.1.1
The ECCP modules use Timers, 1, 2, 3, 4, 6, 8, 10 or 12,
depending on the mode selected. These timers are
available to CCP modules in Capture, Compare or PWM
modes, as shown in

Timer Resource
The assignment of a particular timer to a module is
determined by the timer to ECCP enable bits in the
CCPTMRSx register
between the two modules are depicted in
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.
19.1.2
The pin assignment for ECCPx (capture input,
compare and PWM output) can change, based on
device configuration. The ECCPMX (CONFIG3H<1>)
Configuration bit determines which pins, ECCP1 and
ECCP3, are multiplexed to.
• Default/ECCPMX = 1:
• ECCPMX = 0:
The pin assignment for ECCP2 (capture input,
compare and PWM output) can change, based on
device configuration.
The CCP2MX Configuration bit (CONFIG3H<0>)
determines which pin, ECCP2, is multiplexed to.
• If CCP2MX = 1 (default) – ECCP2 is multiplexed
• If CCP2MX = 0 – ECCP2 is multiplexed to:
- ECCP1 (P1B/P1C) is multiplexed onto RE6
- ECCP3 (P3B/P3C) is multiplexed onto RE4
- ECCP1 (P1B/P1C) is multiplexed onto RH7
- ECCP3 (P3B/P3C) is multiplexed onto RH5
to RC1
- RE7 is the ECCP2 pin with CCP2MX = 0
and RE5
and RE3
and RH6
and RH4.
