28 SLS (SG) override bit 0
1 signal: Set, 0 signal: Not set
29 SLS (SG) override bit 1
1 signal: Set, 0 signal: Not set
30 SLS (SG) override bit 2

re r9719.0 and r9719.1:
These two bits must be considered together.
If SOS/SLS (SBH/SG) is deselected using bit 0, then the assignment of bit 1 is
irrelevant.
If SOS/SLS (SBH/SG) is selected using bit 0, then bit 1 is used to change over
between SOS (SBH) and SLS (SG).
