REJ09B0288-0150

Unconditional trap:

• Conditions

TRAPA instruction executed

• Types

Instruction synchronous, processing-completion type

• Save address

An address of an instruction following TRAPA

• Exception code

′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 TRA[9:2].

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)

Processing-completion type: 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)

• Exception code

′1E0

• Remarks

For details on the user break controller, refer to section 9, User Break Controller.
