Privilege Violation Exception
If the application tries to execute privileged instructions, this exception is issued. The complete
list of priveleged instructions is shown in
routine, the address of the instruction that caused the exception is stored as the stacked return
address.
Table 8-2.
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
mtdr - move to debug 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
