With some instructions, such as instructions that make two accesses to memory, and the
indivisible pair comprising a delayed branch instruction and delay slot instruction, multiple
exceptions occur. Care is required in these cases, as the exception priority order differs from the
normal order.

interrupt request, and the BL bit in SR is 0 (accepted at instruction boundary).
The PC contents immediately after the instruction at which the interrupt is accepted are set in
SPC. The SR and R15 contents at the time of acceptance are set in SSR and SGR.
The code corresponding to the each interrupt source is set in INTEVT. The BL, MD, and RB
bits are set to 1 in SR, and a branch is made to VBR + H'0600.
