8.2.8
Break bus cycle register B (BBRB) is a 16-bit readable/writable register that specifies (1) logic or
internal bus (L or I bus), X bus, or Y bus, (2) CPU cycle or DMAC cycle, (3) instruction fetch or
data access, (4) read/write, and (5) operand size in the break conditions of channel B. BBRB is
initialized to H'0000 by a power-on reset.
Bits 15 to 10—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 9—X/Y Memory Bus Enable (XYE): Selects the logic or internal bus (L or I bus) or X/Y
memory bus as the bus of the channel B break condition.
Bit 8—X or Y Memory Bus Select (XYS): Selects the X bus or the Y bus as the bus of the
channel B break condition.
