Hmm according to the ATMega-32 data sheet you can specify a mask.
"
The Break Point Unit implements Break on Change of Program Flow, Single Step
Break, 2 Program Memory Break Points, and 2 combined Break Points. Together,
the 4
Break Points can be configured as either:
• 4 single Program Memory Break Points
• 3 Single Program Memory Break Point + 1 single Data Memory Break Point
• 2 single Program Memory Break Points + 2 single Data Memory Break Points
• 2 single Program Memory Break Points + 1 Program Memory Break Point with mask
(“range Break Point”)
• 2 single Program Memory Break Points + 1 Data Memory Break Point with mask
(“range Break Point”)
"
I haven't actually tried though.
