Hello,

I have a question about document AN5252 QorIQ LS1046A Design checklist.

On page 27 it states that both TA_BB_TMP_DETECT_B and TA_TMP_DETECT_B, when used they should be pulled down with a 1K resistor. In all reference designs of LS1046A and LS1028 the signals are pulled up.

Since these signals are LOW active. Wont this trigger a tamper right away?

Kind regards,

Remco
