MOVIW Move INDFn to W Syntax: [ label ] MOVIW ++FSRn [ label ] MOVIW --FSRn [ label ] MOVIW FSRn++ [ label ] MOVIW FSRn-- [ label ] MOVIW k[FSRn] Operands: n [0,1] mm [00,01, 10, 11] -32 k 31 Operation: INDFn W Effective address is determined by • FSR + 1 (preincrement) • FSR - 1 (predecrement) • FSR + k (relative offset) After the Move, the FSR value will be either: • FSR + 1 (all increments) • FSR - 1 (all decrements) • Unchanged Status Affected: Z Mode Syntax mm Preincrement ++FSRn 00 Predecrement --FSRn 01 Postincrement FSRn++ 10 Postdecrement FSRn-- 11 Description: This instruction is used to move data between W and one of the indirect registers (INDFn). Before/after this move, the pointer (FSRn) is updated by pre/post incrementing/decrementing it. Note: The INDFn registers are not physical registers. Any instruction that accesses an INDFn register actually accesses the register at the address specified by the FSRn. FSRn is limited to the range 0000h - FFFFh. Incrementing/decrementing it beyond these bounds will cause it to wrap-around. MOVLB Move literal to BSR Syntax: [ label ] MOVLB k Operands: 0 k 31 Operation: k BSR Status Affected: None Description: The 5-bit literal ‘k’ is loaded into the Bank Select Register (BSR). MOVLP Move literal to PCLATH Syntax: [ label ] MOVLP k Operands: 0 k 127 Operation: k PCLATH Status Affected: None Description: The 7-bit literal ‘k’ is loaded into the PCLATH register. MOVLW Move literal to W Syntax: [ label ] MOVLW k Operands: 0 k 255 Operation: k (W) Status Affected: None Description: The 8-bit literal ‘k’ is loaded into W reg- ister. The “don’t cares” will assemble as ‘0’s. Words: 1 Cycles: 1 Example: MOVLW 0x5A After Instruction W = 0x5A MOVWF Move W to f Syntax: [ label ] MOVWF f Operands: 0 f 127 Operation: (W) (f) Status Affected: None Description: Move data from W register to register ‘f’. Words: 1 Cycles: 1 Example: MOVWF OPTION_REG Before Instruction OPTION_REG = 0xFF W = 0x4F After Instruction OPTION_REG = 0x4F W = 0x4F |
