PWM Instruction

Hi
I want to know what is difference between two modes of PWM instruction?

Code:

setup_ccp1(CCP_PWM);
set_pwm1_duty(value);
setup_timer_2(T2_DIV_BY_16,PR,1)

and

Code:

setup_power_pwm(modes, postscale, time_base, period,compare,compare_postscale, dead_time)
set_power_pwm_override(pwm, override, value)
setup_power_pwm_pins(module0,module1,module2,module3)

The first set is used with the ordinary PWM module (CCP) in a PIC. The 2nd set is used with the Power Control PWM module. This module has many more features than the ordinary PWM module (CCP) and it is specifically designed to control motors.
