Pullup resistors on Chip Select lines

2002-12-09 by avi koren

Greetings, this is my first email to this group.

The data sheet for the MC68LK332ACFC16 states that the CSx lines are held at a logic 1 during Reset and out of Reset the CSx lines default to however you drive the data bus during the Reset.  So if configured to be CSx it will continue to drive 1 until that address range has been accessed.  This suggests that Pull ups are NOT NEEDED.  Does anyone have a valid reason for why Pullups should still be utilized on the CSx lines.  

Thanks

Avi
