Bit 5—Execution-Times Break Enable D (ETBED): Enables a channel D execution-times break
condition. When this bit is 1, a user break interrupt is generated when the number of break
conditions that have occurred equals the number of executions specified by the break execution
times register (BETRD).
Bit 5: ETBED
0
1
Bit 4—Reserved: This bit is always read as 0. The write value should always be 0.
Bit 3—Data Break Enable D (DBED): Selects whether a data bus condition is to be included in the
channel D break conditions.
Bit 3: DBED

Bit 2—PC Break Select D (PCBD): Selects whether a channel D instruction fetch cycle break is
effected before or after execution of the instruction.
Bit 2: PCBD
