In Mod 1,2,5,9

If Input clock = 12MHZ

If CKSEL = 0 => Scanner controller run 24MHZ

If CKSEL = 1 => Scanner controller run 32MHZ

In Mode 3:

If MPUCKOE = 1, MPUCLK = (Input clock frequency)/2

If CKSEL = 1 => Scanner controller run (Input clock frequency) /2

If CKSEL = 0 => Scanner controller run (Input clock frequency)

If MPUCKOE = 0, MPUCLK = 0

In Mode 4:

Scanner controller run (Input clock frequency)
