Devices can be modified includes byte device (KnX, KnY, KnM, KnS, T, C, D) and bitdevice (X, Y, M, S). E, F registers cannot be used for modifying constant (K, H) Index registers notused as a modifier can be used as general purpose register.Index register [E], [F]Index registers are 16-bit registers which can be read and written. There are 16 points indicated asE0~E7 and F0~F7. If you need a 32-bit register, you have to designate E. In this case, F will becovered up by E and cannot be used. It is recommended to use instruction DMOVP K0 E to reset E(including F) at power-on.F0 E0E0F016-bit 16-bit32-bitLow wordHigh wordThe combinations of E and F when designating a 32-bit register are:(E0, F0) , (E1, F1) (E2, F2) (E3, F3) (E4, F4) , (E5, F5) (E6, F6) (E7, F7)Example:When X0 = ON and E0 = 8, F0 = 14, D5E0 = D(5+8) = D13, D10F0 = D(10+14) = D24, the contentin D13 will be moved to D24.K14 F0X0K8 E0MOVD5E0 D10F0MOVMOV
