25.5 Exception Trap
V850ES/JH3-E and V850ES/JJ3-E, an illegal opcode exception (ILGOP: Illegal Opcode Trap) is considered as an
exception trap.
25.5.1 Illegal opcode
to 23) = 0111B to 1111B, and sub-opcode (bit 16) = 0B. When such an instruction is executed, an exception trap is
generated.
An exception trap is an interrupt that is requested when the illegal execution of an instruction takes place. In the
An illegal opcode is defined as an instruction with instruction opcode (bits 10 to 5) = 111111B, sub-opcode (bits 26
Caution It is recommended not to use an illegal opcode because instructions may newly be assigned in
(1) Operation
<1> Saves the restored PC to DBPC.
<2> Saves the current PSW to DBPSW.
<3> Sets the PSW.NP, PSW.EP, and PSW.ID bits to 1.
<4> Sets the handler address (00000060H) corresponding to the exception trap to the PC, and transfers
If an exception trap occurs, the CPU performs the following processing, and transfers control to the handler
routine.
The processing of the exception trap is shown below.
