SOLVED: How can I reduce ADC jitter

[Demon]

According to this:

The pull-up is disabled automatically when either TRIS is set to an output or the pin is set as an analog input. These changes to TRIS and ANSEL will override WPU settings.

I can just set all pull-ups ON, leave the unused pins unconnected and forget about them. Then use the others as I wish in ANSEL and TRIS.

The only times I need to be concerned with WPU is on pins that must not be disturbed for whatever special reason.

WPUA = %11111111    '----------------------------------------------------------------'
WPUB = %11111111    '           ALWAYS SET WEAK PULL-UPS ON ALL PINS FIRST           '
WPUC = %11111111    '----------------------------------------------------------------'
                    '       CHANGES TO ANSEL AND TRIS WILL OVERRIDE AS REQUIRED      '
                    '----------------------------------------------------------------'

ANSELA = %00000010                      ' Pin A3 = SW input                 not implemented yet
                                        ' Pin A2 = ADC (B5K)                not implemented yet
                                        ' Pin A1 = ADC (B5K)
                                        ' Pin A0 = ADC (voltage divider)    not implemented yet
ANSELB = %00000000
ANSELC = %00000000

TRISA = %00000010                       ' Pin A3 = SW input                 not implemented yet
                                        ' Pin A2 = ADC input 2              not implemented yet
                                        ' Pin A1 = ADC input 1
                                        ' Pin A0 = ADC input 0              not implemented yet
TRISB = %00000000                       ' Pin B7 = ...not available, ICSPDAT
                                        ' Pin B6 = ...not available, ICSPCLK
TRISC = %11000000                       ' Pin C7 = RX      *** Datasheet requirement, INPUT ***
                                        ' Pin C6 = TX      *** Datasheet requirement, INPUT ***

EDIT: I can even leave PORT at the top in case a pin is left as analog output.

PORTA = %00000000                       '-------------------------------------------' 
PORTB = %00000000                       '       ALWAYS SET PINS LOW FIRST           '
PORTC = %00000000                       '-------------------------------------------'

Or did I miss something important...?
