(10) Slot Illegal Instruction Exception
•
Sources:
Decoding of an undefined instruction in a delay slot
Delayed branch instructions: JMP, JSR, BRA, BRAF, BSR, BSRF, RTS, RTE, BT/S, BF/S
Undefined instruction: H'FFFD
Decoding of an instruction that modifies PC in a delay slot
Instructions that modify PC: JMP, JSR, BRA, BRAF, BSR, BSRF, RTS, RTE, BT, BF,
BT/S, BF/S, TRAPA, LDC Rm,SR, LDC.L @Rm+,SR, ICBI, PREFI
Decoding in user mode of a privileged instruction in a delay slot
Privileged instructions: LDC, STC, RTE, LDTLB, SLEEP, but excluding LDC/STC
instructions that access GBR
Decoding of a PC-relative MOV instruction or MOVA instruction in a delay slot
•
Transition address: VBR + H'000 0100
•
Transition operations:
The PC contents for the preceding delayed branch instruction are saved in SPC. The SR and
R15 contents when this exception occurred are saved in SSR and SGR.
Exception code H'1A0 is set in EXPEVT. The BL, MD, and RB bits are set to 1 in SR, and a
branch is made to PC = VBR + H'0100. Operation is not guaranteed if an undefined code other
than H'FFFD is decoded.
