}
The PC and SR contents for the instruction at which this exception occurred are saved in SPC
and SSR, and the contents of R15 are saved in SGR.
Exception code H'800 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.
SPC = PC;
SSR = SR;
SGR = R15;
EXPEVT = H'00000800;
SR.MD = 1;
SR.RB = 1;
SR.BL = 1;
PC = VBR + H'00000100;
(but excluding undefined instruction H'FFFD), and the LDS, STS, LDS.L, and STS.L
instructions corresponding to FPUL and FPSCR.
