20.1
The user break controller (UBC) provides functions that simplify program debugging. When break
conditions are set in the UBC, a user break interrupt is generated according to the contents of the
bus cycle generated by the CPU. This function makes it easy to design an effective self-monitoring
debugger, enabling programs to be debugged with the chip alone, without using an in-circuit
emulator.
20.1.1
The UBC has the following features.
• Two break channels (A and B)
• The following can be set as break compare conditions:
• An instruction access cycle break can be effected before or after the instruction is executed.
User break interrupts can be generated on independent conditions for channels A and B, or on
sequential conditions (sequential break setting: channel A → channel B).
⎯ Address (selection of 32-bit virtual address and ASID for comparison):
⎯ Data (channel B only, 32-bit mask capability)
⎯ Bus cycle: Instruction access/operand access
⎯ Read/write
⎯ Operand size: Byte/word/longword/quadword
Address: All bits compared/lower 10 bits masked/lower 12 bits masked/lower 16 bits
masked/lower 20 bits masked/all bits masked
ASID: All bits compared/all bits masked
