If no coprocessor can execute the instruction, an Undefined Instruction exception is generated. This is a generic coprocessor instruction. Some of the fields have no functionality defined by the architecture and are free for use by the coprocessor instruction set designer. These are the D bit, the CRd field, and in the Unindexed addressing mode only, the imm8 field. However, coprocessors CP8-CP15 are reserved for use by ARM, and this manual defines the valid STC and STC2 instructions when coproc is in the range p8-p15. For more information see Coprocessor support on page A2-94. In an implementation that includes the Virtualization Extensions, the permitted STC access to a system control register can be trapped to Hyp mode, meaning that an attempt to execute an STC instruction in a Non-secure mode other than Hyp mode, that would be permitted in the absence of the Hyp trap controls, generates a Hyp Trap exception. For more information, see Trapping general CP14 accesses to debug registers on page B1-1260. Note For simplicity, the STC pseudocode does not show this possible trap to Hyp mode. } @encoding (T1) { @word 1 1 1 0 1 1 0 P(1) U(1) D(1) W(1) 0 Rn(4) CRd(4) coproc(4) imm8(8) @syntax { @subid 590 @assert { P == 1 W == 0 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessOffset(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 591 @assert { P == 1 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPreIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 592 @assert { P == 0 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPostIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 593 @assert { P == 0 W == 0 U == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) maccess = MemAccessOffset(reg_N, NULL) option = ZeroExtend(imm8:'00', 32) } @asm stc cp direct_CRd maccess option } } @encoding (T2) { @word 1 1 1 1 1 1 0 P(1) U(1) D(1) W(1) 0 Rn(4) CRd(4) coproc(4) imm8(8) @syntax { @subid 594 @assert { P == 1 W == 0 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessOffset(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 595 @assert { P == 1 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPreIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 596 @assert { P == 0 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPostIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 597 @assert { P == 0 W == 0 U == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) maccess = MemAccessOffset(reg_N, NULL) option = ZeroExtend(imm8:'00', 32) } @asm stc cp direct_CRd maccess option } } @encoding (A1) { @word 1 1 1 0 1 1 0 P(1) U(1) D(1) W(1) 0 Rn(4) CRd(4) coproc(4) imm8(8) @syntax { @subid 598 @assert { P == 1 W == 0 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessOffset(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 599 @assert { P == 1 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPreIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 600 @assert { P == 0 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPostIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 601 @assert { P == 0 W == 0 U == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) maccess = MemAccessOffset(reg_N, NULL) option = ZeroExtend(imm8:'00', 32) } @asm stc cp direct_CRd maccess option } } @encoding (A2) { @word 1 1 1 1 1 1 0 P(1) U(1) D(1) W(1) 0 Rn(4) CRd(4) coproc(4) imm8(8) @syntax { @subid 602 @assert { P == 1 W == 0 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessOffset(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 603 @assert { P == 1 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPreIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 604 @assert { P == 0 W == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) imm32 = ZeroExtend(imm8:'00', 32) maccess = MemAccessPostIndexed(reg_N, imm32) } @asm stc cp direct_CRd maccess } @syntax { @subid 605 @assert { P == 0 W == 0 U == 1 } @conv { cp = CoProcessor(coproc) direct_CRd = UInt(CRd) reg_N = Register(Rn) maccess = MemAccessOffset(reg_N, NULL) option = ZeroExtend(imm8:'00', 32) } @asm stc cp direct_CRd maccess option } }
