Accessing the S3_<op1>_<Cn>_<Cm>_<op2>
Accesses to this register use the following encodings:
MRS <Xt>, S3_<op1>_C<Cn>_C<Cm>_<op2>
op0 | op1 | CRn | CRm | op2 |
---|---|---|---|---|
0b11 | op1[2:0] | 0b1x11 | Cm[3:0] | op2[2:0] |
if PSTATE.EL == EL1 then if EL2Enabled() && HCR_EL2.TIDCP == '1' then AArch64.SystemAccessTrap(EL2, 0x18); else IMPLEMENTATION_DEFINED ""; else IMPLEMENTATION_DEFINED "";
MSR S3_<op1>_C<Cn>_C<Cm>_<op2>, <Xt>
op0 | op1 | CRn | CRm | op2 |
---|---|---|---|---|
0b11 | op1[2:0] | 0b1x11 | Cm[3:0] | op2[2:0] |
if PSTATE.EL == EL1 then if EL2Enabled() && HCR_EL2.TIDCP == '1' then AArch64.SystemAccessTrap(EL2, 0x18); else IMPLEMENTATION_DEFINED ""; else IMPLEMENTATION_DEFINED "";
