⎯ Channel 1
With the above settings, the user break occurs after executing the instruction at address
H'00008000 to H'00008FFE where ASID is H'80 or before executing the instruction at address
H'00008010 to H'00008016 where ASID is H'70.
Register settings: CBR0 = H'40800023 / CRR0 = H'00002001 / CAR0 = H'00123456 /
CAMR0 = H'00000000 / CBR1 = H'4070A025 / CRR1 = H'00002001 / CAR1 =
H'000ABCDE / CAMR1 = H'000000FF / CDR1 = H'0000A512 / CDMR1 = H'00000000 /
CETR1 = H'00000000 / CBCR = H'00000000
Specified conditions: Independent for channels 0 and 1
⎯ Channel 0
⎯ Channel 1
With these settings, the user break occurs for channel 0 for the following accesses: longword
read access to address H'000123454, word read access to address H'000123456, byte read
access to address H'000123456 where ASID is H'80. The user break occurs for channel 1 when
word H'A512 is written to address H'000ABC00 to H'000ABCFE where ASID is H'70.
