Section 11 User Break Controller (UBC)
11.2.2
BAMRA is a 32-bit readable/writable register. BAMRA specifies bits masked in the break address
specified by BARA.
11.2.3
Break bus cycle register A (BBRA) is a 16-bit readable/writable register, which specifies (1) L bus
cycle or I bus cycle, (2) instruction fetch or data access, (3) read or write, and (4) operand size in
the break conditions of channel A.

These bits are always read as 0. The write value
should always be 0.
L Bus Cycle/I Bus Cycle Select A
Select the L bus cycle or I bus cycle as the bus cycle
of the channel A break condition.
00: Condition comparison is not performed
01: The break condition is the L bus cycle
10: The break condition is the I bus cycle
11: The break condition is the L bus cycle
the break condition
is not included in the break condition
