Bit 23—CPU Condition Match Flag B (CMFCB): This flag is set to 1 when a CPU bus cycle
condition, among the break conditions set for channel B, 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 22—DMAC Condition Match Flag B (CMFPB): This flag is set to 1 when an on-chip DMAC
bus cycle condition, among the break conditions set for channel B, 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 21—Reserved: This bit is always read as 0. The write value should always be 0.
Bits 20 and 19—Sequence Condition Select (SEQ1, SEQ0): These bits select independent or
sequential conditions for channels A, B, C, and D.
