If i just set the CCP1CON to full bridge forward/reverse, it will automatically configure the pins P1A, P1B, P1C,P1D ?

for example :
Quote:
setup_ccp1(CCP_PWM_FULL_BRIDGE | CCP_PWM_H_H);
delay_ms(5000);

// Run in reverse for 5 seconds.
setup_ccp1(CCP_PWM_FULL_BRIDGE_REV | CCP_PWM_H_H);
delay_ms(5000);


can this simple code run forward in first 5 second then run reverse in next 5 second?

Yes, that should work OK.

The data sheet outlines the precautions you may need to take when attempting to reverse direction.
