Load the low 16-bits of RaH with the immediate value #16FLoHex. #16FLoHex
Description
represents the lower 16-bits of an IEEE 32-bit floating-point value. The upper 16-bits of
RaH will not be modified. MOVXI can be combined with the MOVIZ or MOVIZF32
instruction to initialize all 32-bits of a RaH register.
RaH[15:0] = #16FLoHex
RaH[31:16] = Unchanged
