The user break controller (UBC) provides versatile functions to facilitate program debugging.
These functions help to ease creation of a self-monitor/debugger, which allows easy program
debugging using this LSI alone, without using the in-circuit emulator. Various break conditions
can be set in the UBC: instruction fetch or read/write access of an operand, operand size, data
contents, address value, and program stop timing for instruction fetch.
29.1
1. The following break conditions can be set.
• Address
• Data
• Bus cycle
• Read or write access
• Operand sizes
2. The user-designated exception handling routine for the user break condition can be executed.
3. Pre-instruction-execution or post-instruction-execution can be selected as the PC break timing.
4. A maximum of 2
Break channels: Two (channels 0 and 1)
User break conditions can be set independently for channels 0 and 1, and can also be set as a
single sequential condition for the two channels, that is, a sequential break. (Sequential break
involves two cases such that the channel 0 break condition is satisfied in a certain bus cycle
and then the channel 1 break condition is satisfied in a different bus cycle, and vice versa.)
When 40 bits containing ASID and 32-bit address are compared with the specified value, all
the ASID bits can be compared or masked.
32-bit address can be masked bit by bit, allowing the user to mask the address in desired page
sizes such as lower 12 bits (4-Kbyte page) and lower 10 bits (1-Kbyte page).
32 bits can be masked only for channel 1.
The program can break either for instruction fetch (PC break) or operand access.
Byte, word, longword, and quadword are supported.
for channel 1).
