TMR0 ON 16F877A

Is there a way to force the tmr0 to increment every instruction cycle?
when using set_up_timer0(RTCC_INTERNAL) the timer increments every 2 instruction cycles. This is because the prescaler is assigned to it. When i try to assigne the prescaler to the WDT nothing works. I've tried the asm sequence shown in the midrange PIC manual to no avail. the code reccomended by microchip for doing this is shown below. Any help would be appreciated

void timer01to1(void)
{
#define RP0 5
#define RP1 6

#byte TMR0=0x101
#byte STATUS=0x03
#byte OPTION_REG=0x81

#asm
bsf STATUS,RP0;
movlw 0xc7;
movwf OPTION_REG;
bcf STATUS,RP0;
clrf TMR0;
bsf status,RP1;
movlw 0xcf;
movwf OPTION_REG;
clrwdt;
movlw 0xc8;
movwf OPTION_REG;
bcf STATUS,RP0;
#endasm
}

thanks

Try this

setup_counters (RTCC_INTERNAL, WDT_2304MS);
