  • To lock with 0-delay PLL2....

    Since divider for ch6&7 = 4, Need to update PLL2_N = 2 to 1 and set PLL2_NBYPASS_DIV2_FB = 1, (since CH6 is doing the /4 now).  For this set R116 = 0x01 and R326[6] = 1.

    Appears that R232 should be set to 0x01 to enable feedback for CH6.  Not 0x10.  It appears that R232 upper and lower nibble of R232 are swapped.  I'll put a note in for datasheet update.
