@title VMOV (between two ARM core registers and a doubleword extension register)
@id 310
@desc {
This instruction copies two words from two ARM core registers into a doubleword extension register, or from a doubleword extension register to two ARM core registers. Depending on settings in the CPACR, NSACR, HCPTR, and FPEXC registers, and the security state and mode in which the instruction is executed, an attempt to execute the instruction might be UNDEFINED, or trapped to Hyp mode. Summary of general controls of CP10 and CP11 functionality on page B1-1230 and Summary of access controls for Advanced SIMD functionality on page B1-1232 summarize these controls.
