Address: H'00008404, Address mask: H'00000FFF, ASID = H'80
Bus cycle: L bus/instruction fetch (after instruction execution)/read (operand size is not
included in the condition)

Data:
H'00000000, Data mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/read (operand size is not
included in the condition)
A user break occurs after an instruction with ASID = H’80 and addresses H'00008000 to
H'00008FFE is executed or before an instruction with ASID = H’70 and addresses H'00008010
to H'00008016 are executed.

Bus cycle: L bus/data access/write/word
On channel A, a user break occurs with longword read from ASID = H’80 and address
H'00123454, word read from address H'00123456, or byte read from address H'00123456. On
channel B, a user break occurs when word H'A512 is written in ASID = H’70 and addresses
H'000ABC00 to H'000ABCFE.
