Secure Monitor Call causes a Secure Monitor Call exception. For more information see Secure Monitor Call (SMC) exception on page B1-1210. 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.
