In the case of a post-execution break, the PC contents for the instruction following the
instruction at which the breakpoint is set are set in SPC. In the case of a pre-execution break,
the PC contents for the instruction at which the breakpoint is set are set in SPC.
The SR and R15 contents when the break occurred are saved in SSR and SGR. Exception code
H'1E0 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. It is
also possible to branch to PC = DBR.
For details of PC, etc., when a data break is set, see section 29, User Break Controller (UBC).
SPC = (pre_execution break? PC : PC + 2);
SSR = SR;
SGR = R15;
EXPEVT = H'0000 01E0;
SR.MD = 1;
SR.RB = 1;
SR.BL = 1;
PC = (BRCR.UBDE==1 ? DBR : VBR + H'0000 0100);
