Section 4 Exception Handling
• SPC when an Exception Occurs: The PC saved to the SPC when an exception occurs is as
• Initial register values after reset
• Ensure that an exception is not generated at an RTE instruction delay slot, as operation is not
• When the BL bit in the SR register is set to 1, ensure that a TLB-related exception or address

a delay slot, however, the PC of the immediately prior delayed branch instruction is set in
the SPC. If the condition of the conditional delayed branch instruction is not satisfied, the
delay slot PC is set in SPC.

conditional branch instruction, however, the branch destination PC is set in SPC. If the
condition of the conditional delayed branch instruction is not satisfied, the delay slot PC is
set in SPC.
