Instruction
Format and Description
Breakpoint
BREAK
Initiate breakpoint trap, immediately transferring control to exception
handler.
System Call
SYSCALL
Initiate system call trap, immediately transferring control to exception
handler.
Table 4.13 CP0 Instructions
Instruction
Format and Description
Exception Return
1
ERET (R4000 Mode)
Load the PC from ErrorEPC(SR2 = 1:Error Exception) or
EPC(SR2=0:Exception) and clear ERL bit (SR2 = 1) or EXL bit (SR2 = 0)
in the Status Register. SR2 is Status register bit[2].
Move from CP0
MFC0 rt, rd
Load contents of CP0 register
rd
into CPU register
rt
.
Move to CP0
MTC0 rt, rd
Load contents of CPU register
rt
into CP0 register
rd
.
Restore From Exception
1
RFE (R3000 Mode)
Restore previous interrupt mask and mode bits of the Status register into
current status bits. Restore old status bits into previous status bits.
Wait for Interrupt
WAITI
Stop execution of instructions and place the processor in a power save
(stall) condition until a hardware interrupt, NMI (nonmaskable interrupt), or
reset is received.
1.
ERET
and
RFE
cannot be legal at the same time. The one that is not legal causes a reserved
instruction exception.
