General_illegal_instruction_exception()
{
}
⎯ Decoding of an undefined instruction not in a delay slot
⎯ Decoding in user mode of a privileged instruction not in a delay slot
The PC and SR contents for the instruction at which this exception occurred are saved in SPC
and SSR. The R15 contents at this time are saved in SGR.
Exception code H'180 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.
General Illegal Instruction Exception
SPC = PC;
SSR = SR;
SGR = R15;
EXPEVT = H'0000 0180;
SR.MD = 1;
SR.RB = 1;
SR.BL = 1;
PC = VBR + H'0000 0100;
Delayed branch instructions: JMP, JSR, BRA, BRAF, BSR, BSRF, RTS, RTE, BT/S, BF/S
Undefined instruction: H'FFFD
Privileged instructions: LDC, STC, RTE, LDTLB, SLEEP, but excluding LDC/STC
instructions that access GBR
