Hello!
I am looking at the LMKDB12xx and LMKDB11xx family (they share a datasheet), and I am confused about the default behavior of the OE# pins.
The following variants mention in their pin function tables an "Internal Pull-up resistor" on the OEx# pins:
- LMKDB1102
- LMKDB1202
- LMKDB1204

The following variants mention in their pin function tables an "Internal Pull-down resistor" on the OEx# pins:
- LMKDB1104
- LMKDB1108
- LMKDB1120

This is a little strange but not suspicious on its own. I became confused when I saw the LMKDB1x02 Evaluation Module user manual, where on page 4, table 3-3 it shows "Low" as the default input value.
So which is it for LMKDB1102 and the others that mentioned "Internal Pull-up resistors"? Is an external pull-down resistor required as the datasheet suggests, or is the default value "low" as the evaluation module suggests? Is there a typo in the datasheet or the evaluation module user manual or am I missing something?
Thanks!
