In looking at the DM6446 REV-F datasheet, I am confused if certain terminal pins have internal pullups or pulldowns. I am attempting to minimize logic required to configure the board in reset.
Specifically, The AEAW(YOUT4-0) and COUT(COUT3-0) pins have IPD internal pulldowns documented in Table 2-5 (page 27) and Table 2-9 (page 29), and are also shown as part of the "low-group" in Figure 6-9 on page 102. Yet, in that same figure 6-9, they are documented as being in the "Z-group" with IPU internal pullUPS. How can they be in both "low" and "Z" groups?
Do they have internal pullups or pulldowns? Does that change during reset?
I am not quite sure how to read this.
