OWOUT Glitch

[retepsnikrep]

I'm using a PIC18F2680 at 32mhz

I'm struggling with communicating with a DS18B20 sensor.

I plugged my Saleae Logic analyser into the system and can see there is a glitch in the OWOUT $33 rom command at about 2.2ms.
So the result is garbage..

The DS18B20 does respond to the reset request though just prior to the above.

DEFINE OSC 32           '8mhz Clock (x4 = 32mhz)
OSCCON = %01110000      'Internal 32 mhz Osc and stable 
OSCTUNE = %01000000     'Enable PLL 8mhz x 4 
WDTCON = %00010101		'Set watchdog Timer for 1 second 
CCP1CON= %00001100		'CCP1 Module PWM Mode
HLVDCON= %00000000		'HLVCON Disabled
T1CON  = %00110000		'$30 = Prescaler 1:8, TMR1 OFF	
TRISA = %00000011 		'SET PORTA0.1,2 AS INPUT, REST AS OUTPUTS
TRISB = %00001000 		'SET PORTB.3 AS INPUT REST AS OUTPUTS
TRISC = %10000000 		'SET PORTC.7 AS INPUT REST AS OUTPUTS	

DQ          var PORTC.4     'One-wire Data-Pin "DQ" on PortC.4


MainLoop:
 
    OWOUT DQ, 1, [$33]  ' Issue Read ROM command
    OWIN DQ, 0, [STR ID\8]' Read 64-bit device data into the 8-byte array "ID"

    lcdout LCM,L22,"Ser ",HEX2 ID[1],HEX2 ID[2],HEX2 ID[3],HEX2 ID[4],HEX2 ID[5],HEX2 ID[6],"h"
    lcdout LCM,L32,"CRC ",HEX2 ID[7],"h"
    PAUSE 500         '500ms second pause, replace sensor for next read
    lcdout LCM,LCL       

goto MainLoop

See the weird glitch in the $33 bits being sent..

Any ideas.
