Usage

Store Register Halfword (unprivileged) stores a halfword from a 32-bit register to memory. The address that is used for the store is calculated from a base register and an immediate offset.

The memory is restricted as if execution is at EL0 when:

• Executing at EL1.
• Executing at EL2, in ARMv8.1, with HCR_EL2.{E2H, TGE} set to {1, 1}.

Otherwise, the access permission is for the Exception level at which the instruction is executed. For information about memory accesses, see Load/Store addressing modes in the ARM Architecture Reference Manual ARMv8, for ARMv8-A architecture profile.
