Convert 16-Bit Integer to 32-Bit Floating-Point Value
MRa | CLA floating-point destination register (MR0 to MR3) |
mem16 | 16-bit source memory location to be converted |
LSW: mmmm mmmm mmmm mmmm
MSW: 0111 0101 00aa addr
Convert the 16-bit signed integer indicated by the mem16 pointer to a 32-bit floating-point value and store the result in MRa.
MRa = MI16TOF32[mem16];
This instruction does not affect any flags:
Flag | TF | ZF | NF | LUF | LVF |

This is a single-cycle instruction:
; Assume A = 4 (0x0004)
; B = -4 (0xFFFC)
MI16TOF32 MR0, @_A ; MR0 = MI16TOF32(A) = 4.0 (0x40800000)
MI16TOF32 MR1, @_B ; MR1 = MI16TOF32(B) = -4.0 (0xC0800000
