What is the role of CCPxCON?
CCPxCON – refers to CCP one or CCP two control register, supporting the mode selection and access to the two least significant bits.. CCPxL – refers to CCP one or CCP two is used to store low byte value in Capture or compare operation and as entry register in PWM mode.
What is PWM and CCP?
PWM Mode (PWM) In Pulse Width Modulation mode, the CCPx pin produces up to a 10-bit resolution PWM output. Since the CCP1 pin is multiplexed with the PORTC data latch, the TRISC<2> bit must be cleared to make the CCP1 pin an output. Figure shows a simplified block diagram of the CCP module in PWM mode.
What will happen if CCP1CON is loaded by 0x0A?
When CCP1CON = 10 (0x0A), CCP1 module is configured for compare mode and is set up so that upon a compare match of CCPR1 and TMR1, RC2 is unaffected.
How many ECCP modules does the pic18f548 have?

Which mode is enhanced in ECCP?
PWM
The Enhanced CCP (ECCP), available on some of Microchip’s devices, differs from the regular CCP module in that it provides enhanced PWM functionality – namely, full-bridge and half- bridge support, programmable dead-band delay, and enhanced PWM auto-shutdown.
What is CCP and ECCP?
Select PIC24 family devices incorporate one or more combined Capture/Compare/PWM (CCP) modules. The standard CCP module provides a single PWM output, while the ECCP module can drive up to four PWM outputs. The enhanced PWM features make the ECCP module suitable for a variety of power and motor con- trol applications.
What is timer capture?
“Capture” mode saves the current timer value into the CCP registers when a specific event occurs (usually a transition on the CCP pin). “Compare” mode continually compares the value in the CCP register with the timer value, and triggers an interrupt or a transition on the CCP pin when the two values match. 7/11/2018.
What is a CCP module?
The abbreviation CCP stands for Capture/Compare/PWM. The CCP module is a peripheral which allows the user to time and control different events. Capture Mode, allows timing for the duration of an event. This circuit gives insight into the current state of a register which constantly changes its value.
Which bits of CCP1CON register decides the decimal fraction of duty cycle?
CCPR1 Register The higher 8 bits (MSBs) DC1B9: DC1B2 of this register are in CCPR1L register (8-bit) and lower 2 bits(LSBs) DC1B1: DC1B0, which are used for a decimal portion in duty cycle, are in CCP1CON register at bit 5 and 4 respectively.
What is capture mode in timer?
“Capture” mode saves the current timer value into the CCP registers when a specific event occurs (usually a transition on the CCP pin). “Compare” mode continually compares the value in the CCP register with the timer value, and triggers an interrupt or a transition on the CCP pin when the two values match.
Which timer is used for capture mode in CCP module?
To set the CCP module in Capture Mode we need to configure both the CCP and Timer Control registers. Timer 1 or Timer 3 can be chosen to source the CCP module.
