DTLB Modified Exception
Table 8-3.
The DTLB Modified exception is generated when a data memory write hits a valid TLB entry, but
the Dirty bit of the entry is 0. This indicates that the page is not writable.
Privileged Instructions
csrf - clear status register flag
cache - perform cache operation
tlbr - read addressed TLB entry into
TLBEHI and TLBELO
tlbw - write TLB entry registers into
TLB
tlbs - search TLB for entry matching
TLBEHI[VPN]
mtsr - move to system register
mfsr - move from system register
mfdr - move from debug register
rete- return from exception
rets - return from supervisor call
retd - return from debug mode
sleep - sleep
ssrf - set status register flag
- move to debug register
RSR_EX = SR;
RAR_EX = PC;
TLBEAR = FAILING_VIRTUAL_ADDRESS;
TLBEHI[VPN] = FAILING_PAGE_NUMBER;
TLBEHI[I] = 0;
SR[R] = 0;
SR[J] = 0;
SR[M2:M0] = B’110;
SR[EM] = 1;
SR[GM] = 1;
PC = EVBA + 0x44;
List of instructions which can only execute in privileged modes.
