Has anyone experience with the DDC lines of the STPC Elite. I could'nt access them. They are always high (due to the pullups). The will never toggle to low. I used chip register 95h.

There is a mistake in the documentation. They are controlled via register 97h not 95h.

And the bit sequence is inverted.

Bit 0: W_DDC1(CLK) Bit 1: W_DDC0(DAT) Bit 2: R_DDC1(CLK) Bit 3: R_DDC0(DAT) Why could this not be found in the Elite errata?
