The output at the LML pin is in "1" when either LML1, LML2, or LMR is in "1".
These general latches are for external control. LA, LB, LC, and LD correspond to
the external pin symbols and are set independently. Initially, all latches are set to "0".
Sets the corresponding latches listed above to "0".
