The PC and SR contents for the instruction immediately after this exception is accepted are
saved in SPC and SSR. The R15 contents at this time are saved in SGR.
Exception code H'1C0 is set in INTEVT. The BL, MD, and RB bits are set to 1 in SR, and a
branch is made to PC = VBR + H'0600. When the BL bit in SR is 0, this interrupt is not
masked by the interrupt mask bits in SR, and is accepted at the highest priority level. When the
BL bit in SR is 1, a software setting can specify whether this interrupt is to be masked or
accepted.
