Unconditional trap:
•
Conditions
TRAPA instruction executed
•
Types
Instruction synchronous, processing-completion type
•
Save address
An address of an instruction following TRAPA
•
Exception code
H'160
•
Remarks
The exception is a processing-completion type, so PC of the instruction after the TRAPA
instruction is saved to SPC. The 8-bit immediate value in the TRAPA instruction is quadrupled
and set in TRA9 to TRA0.
User break point trap:
•
Conditions
When a break condition set in the user break controller is satisfied
•
Types
Break (L bus) before instruction execution: Instruction synchronous, re-execution type
Operand break (L bus): Instruction synchronous, processing-completion type
Data break (L bus): Instruction asynchronous, processing-completion type
I bus break: Instruction asynchronous, processing-completion type
•
Save address
Re-execution type: An address of the instruction where a break occurs (a delayed branch
instruction address if an instruction is assigned to a delay slot)
Operand break (L bus): An address of the instruction following the instruction where a break
occurs (a delayed branch instruction destination address if an instruction is assigned to a delay
slot)
Data break (L bus): Instruction asynchronous, processing-completion type
•
Exception code
H'1E0
•
Remarks
For details on user break controller, refer to section 11, User Break Controller (UBC).
