SMC is available only from software executing at PL1 or higher. It is UNDEFINED in User mode. In an implementation that includes the Virtualization Extensions: • If HCR.TSC is set to 1, execution of an SMC instruction in a Non-secure PL1 mode generates a Hyp Trap exception, regardless of the value of SCR.SCD. For more information see Trapping use of the SMC instruction on page B1-1254. • Otherwise, when SCR.SCD is set to 1, the SMC instruction is: — UNDEFINED in Non-secure state — UNPREDICTABLE if executed in a Secure PL1 mode. } @encoding (T1) { @word 1 1 1 1 0 1 1 1 1 1 1 1 imm4(4) 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 @syntax { @subid 3817 @conv { direct_imm4 = UInt(imm4) } @asm smc direct_imm4 } } @encoding (A1) { @word cond(4) 0 0 0 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 imm4(4) @syntax { @subid 3818 @conv { direct_imm4 = UInt(imm4) } @asm smc direct_imm4 @rules { check g_arm_instruction_set_cond(cond) } } }
