HPWM and timer 1 on pic16f77

[n qwerty]

im using a pic16f77 and am using the ccp in pwm to generate a 1khz square wave by the following

DEFINE CCP1_REG PORTC
DEFINE CCP1_BIT 2

HPWM 1,127,1000

this works fine until the main program starts (which uses the timer1 module for a counter) when the frequency changes to around 8Khz and i have no idea. Is there some port i need to set to keep it in hpwm mode or am is there something else going on

thanks

Probably you did something bad somewhere, this PIC use TIMER 2 for HPWM.

Post your whole code here.. unless we can't help.

seem to have sorted it. appears something to do with PIR and PIE registers. commented it out and works as before but without the frequency changing
