3.5.6
When an MMU exception or CPU address error occurs immediately before or within a repeat
loop, the PC of the instruction that generated the exception cannot be saved in SPC correctly and
the repeat loop cannot be restarted after returning from the exception handler. EXPEVT is set to
H'070 in cases of TLB miss, TLB invalid, and CPU address error. EXPEVT is set to H'0D0 in
case of TLB protection violation. Figure 3.14 shows where such cases occur.
In a repeat loop of 4 or more instructions, only the last 4 instructions are relevant (see figure 3.14
(4)).
MMU Exception in Repeat Loop
(1) 1 instruction repeated (inst1, SR.RC=2)
(2) 2 instructions repeated (inst1 and inst2, SR.RC=2)
(3) 3 instructions repeated (inst1, inst2 and inst3, SR.RC=2)
