CLKOUT pin and power dissipation - ADSP2181

Hi,
Why should the CLKOUT pin in ADSP2181 may also be disabled to reduce
external power dissipation ? How does it contribute to power
dissipation ?

( I posted this earlier. But it did not appear :(:( ).

Thx in advans,

Without looking at the ADSP2181 datasheet, I think I can safely say
that power is reduced because you have one less output driver active.
The power dissipated by the CLKOUT pin would depend mainly upon the
capacitive load (i=c*dv/dt) that it's driving.
