REJ09B0292-0200

Bit 12—Reserved: This bit is always read as 0. The write value should always be 0.

Bit 11—Data Break Enable C (DBEC): Selects whether a data bus condition is to be included in

the channel C break conditions.

Bit 11: DBEC

Description

Data bus condition is not included in channel C conditions

(Initial value)

Data bus condition is included in channel C conditions

Bit 10—PC Break Select C (PCBC): Selects whether a channel C instruction fetch cycle break is

effected before or after execution of the instruction.

Bit 10: PCBC

Description

Channel C instruction fetch cycle break is effected before instruction execution

(Initial value)

Channel C instruction fetch cycle break is effected after instruction execution

Bits 9 and 8—Reserved: These bits are always read as 0. The write value should always be 0.

Bit 7—CPU Condition Match Flag D (CMFCD): This flag is set to 1 when a CPU bus cycle

condition, among the break conditions set for channel D, is satisfied. This flag is not cleared to 0

(if the flag setting is to be checked again after it has once been set, the flag must be cleared by a

write).

Bit 7: CMFCD

Description

User break interrupt has not been generated by a channel D CPU cycle

condition

(Initial value)

User break interrupt has been generated by a channel D CPU cycle condition

Bit 6—DMAC Condition Match Flag D (CMFPD): This flag is set to 1 when a DMAC bus cycle

condition, among the break conditions set for channel D, is satisfied. This flag is not cleared to 0

(if the flag setting is to be checked again after it has once been set, the flag must be cleared by a

write).

Bit 6: CMFPD

Description

User break interrupt has not been generated by a channel D on-chip DMAC

cycle condition

(Initial value)

User break interrupt has been generated by a channel D on-chip DMAC cycle

condition
