This instruction divides one floating-point value by another floating-point value and writes the result to a third floating-point register. 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 summarizes these controls.
