* Mute & Standby outputs:
GP1 represents the Mute or Standby output depending on the definition in address 0Bh. In case you think it is
better or need to define the respective output on the expander, select address 0Bh and select the respective
option-entry. The timing between the different states are settable in the addresses 11h and 12h. If T1 = 'Time
between mute and play’ and T2 = 'Time between mute and standby’ then we can visualize the states as
following:
