Where:

Vd

Vn

Bitwise Select. This instruction sets each bit in the destination SIMD and FP register to the corresponding bit from the first source SIMD and FP register when the original destination bit was 1, otherwise from the second source SIMD and FP register.

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
