I just downloaded the revision 2.21 (October 2009) of HCS12X microcontroller data sheet, named MC9S12XDP512RMV2.
It seems to me that table 1-12 on page 73, which shows the interrupt vector locators, contains some duplicate entries. For example, "Vector base + $D2" is both enlisted as dedicated to ADT0 and reserved. Same for entries "Vector base + $BC", $AE-$98, $8A-$88, $86-$84, and $82. Am I wrong?
