This works really well in XC8

//********** DELAY #uS **********
void ds18b20_delay_us(volatile unsigned char us_count)		//input value will be in W. "Volatile" attribute prevents an "unused" warning.
	addlw   0xFF					;1 clk  0xff=-1, 0xfe=-2, etc			//<<<<<<<<<<<<<<<<<<<<SET AS NEEDED
	btfsc   STATUS,0				;1 clk   will be clear if W was smaller than 1,2,etc
	goto    temp_ds18b20_dlyloop	;2 clks
