TLB invalid exception
PC and SR of the instruction that generated the exception are saved to SPC and SSR,
respectively. If the exception occurred during a read, H'040 is set in EXPEVT; if the exception
occurred during a write, H'060 is set in EXPEVT. The BL, MD, and RB bits in SR are set to 1
and a branch occurs to PC
Initial page write exception
PC and SR of the instruction that generated the exception are saved to SPC and SSR,
respectively. H'080 is set in EXPEVT. The BL, MD, and RB bits in SR are set to 1 and a
branch occurs to PC
TLB protection exception
PC and SR of the instruction that generated the exception are saved to SPC and SSR,
respectively. If the exception occurred during a read, H'0A0 is set in EXPEVT; if the exception
occurred during a write, H'0C0 is set in EXPEVT. The BL, MD, and RB bits in SR are set to 1
and a branch occurs to PC
Conditions: Comparison of TLB addresses shows address match but the TLB entry valid
bit (V) is 0.
Operations: The virtual address (32 bits) that caused the exception is set in TEA and the
corresponding virtual page number (22 bits) is set in PTEH (31–10). The ASID of PTEH
indicates the ASID at the time the exception occurred. The way that generated the
exception is set in the RC bits in MMUCR.
Conditions: A hit occurred to the TLB for a store access, but the TLB entry data bit (D) is
0.
This occurs for initial writes to the page registered by the load.
Operations: The virtual address (32 bits) that caused the exception is set in TEA and the
corresponding virtual page number (22 bits) is set in PTEH (31–10). The ASID of PTEH
indicates the ASID at the time the exception occurred. The way that generated the
exception is set in the RC bit in MMUCR.
Conditions: When a hit access violates the TLB protection information (PR bits) shown
below:
Operations: The virtual address (32 bits) that caused the exception is set in TEA and the
corresponding virtual page number (22 bits) is set in PTEH (31–10). The ASID of PTEH
indicates the ASID at the time the exception occurred. The way that generated the
exception is set in the RC bits in MMUCR.
