    If PLLEN in Configuration Words = 1, SPLLEN bit is ignored. 4x PLL is always enabled (subject to oscillator requirements)

    why are selecting Timer1 oscillator for fosc ? its incapable of 32mhz operation or pll

    Thanks!
    Yes it was my error - set OSCCON=%11110000 and now it seems to be working correctly.
