Unsigned Maximum Pairwise. This instruction creates a vector by concatenating the vector elements of the first source SIMD and FP register after the vector elements of the second source SIMD and FP register, reads each pair of adjacent vector elements in the two source SIMD and FP registers, writes the largest of each pair of unsigned integer values into a vector, and writes the vector to the destination 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.
