Rev.6.00 Mar. 27, 2009 Page 144 of 1036
REJ09B0254-0600
⎯ Operations: The logical address (32 bits) that caused the exception is set in TEA. The PC
⎯ Conditions: TRAPA instruction executed
⎯ Operations: The exception is a processing-completion type, so the PC of the instruction
⎯ Conditions:
and SR of the instruction that generated the exception are saved to the SPC and SSR,
respectively. If the exception occurred during a read, H'0E0 is set in EXPEVT; if the
exception occurred during a write, H'100 is set in EXPEVT. The BL, MD, and RB bits in
SR are set to 1 and a branch occurs to PC = VBR + H'0100. See section 3.5.5, Processing
Flow in Event of MMU Exception, for more information.
after the TRAPA instruction is saved to the SPC. SR from the time when the TRAPA
instruction was executing is saved to SSR. The 8-bit immediate value in the TRAPA
instruction is quadrupled and set in TRA (9 to 0). H'160 is set in EXPEVT. The BL, MD,
and RB bits in SR are set to 1 and a branch occurs to PC = VBR + H'0100.
a. When undefined code not in a delay slot is decoded
b. When a privileged instruction not in a delay slot is decoded in user mode
c. When a DSP instruction not in a delay slot is decoded without DSP extension
d. When an instruction that rewrites the PC/SR/RS/RE in the last three instructions of
Delay branch instructions: JMP, JSR, BRA, BRAF, BSR, BSRF, RTS, RTE, BT/S,
BF/S
Undefined instruction: H'Fxxx
Privileged instructions: LDC, STC, RTE, LDTLB, SLEEP; instructions that access
GBR with LDC/STC are not privileged instructions.
