Document Table of Contents Strobes

The first pins listed in the pin address lookup table are the strobes. They are also identified by bits[7:4] = 0xE. For separate strobes, the input strobe pin placement always take precedence. For differential and complementary strobes, the positive pin is the lower index.

Note: You can modify the output phase of differential strobes by writing to either the positive or negative pin. Only one write is necessary. This is also the case for output-only complementary strobes.
