Debug control register 0
Detect condition select bits (Note 1)
000: Do not select.
001: Address matching detection 0
010: Address matching detection 1
011: Address matching detection 2
100: Do not select.
101: Out-of-address-area detection
110: Do not select.
111: Do not select.
Fix this bit to “0” (Note 1).
Detect enable bit (Note 1)
0: Detection disabled.
1: Detection enabled.
Fix this bit to “0” (Note 1).

Debug control register 1
Fix this bit to “0” (Note 1).
“0” at read (Note 1).
Address compare register access enable bit (Note 2)
0: Disabled
1: Enabled
Fix this bit to “1” when using the debug function.
Fix this bit to “0” (Note 1).
While debugger is not used, “0” at read.
While debugger is used, “1” at read.
Address-matching-detection 2 decision bit
Valid when address matching detection 2 is selected.
0: Matches with the contents of the address compare register 0.
1: Matches with the contents of the address compare register 1.
“0” at read.

Notes 1: At power-on reset, these bits = “0”; at hardware reset or software reset, these bits retain
the value just before reset.
2: Set this bit to “1” with the instruction just before the address compare register 0, 1
(addresses 6816 to 6D16) is accessed. And then, clear this bit to “0” with the instruction
just after the access.
