6.3.4. SDVO / PEG Multiplexed Signals

The Kontron Compact Computers (KCC) smartModuleX945 uses the upper PEG signals to multiplex the two

SDVO channels. If the SDVO is in use, the PEG function is not available. Intel allows, with the P45CM,

multiplexing the SDVO on the lower or, alternatively, on the upper PEG lines. KCC's implementation for

multiplexing the upper PEG lines are defined in the table below.
