329 / 398 page  2010 Microchip Technology Inc. Preliminary DS41413A-page 329 PIC12F/LF1822/16F/LF1823 MOVWI Move W to INDFn Syntax: [ label ] MOVWI ++FSRn [ label ] MOVWI --FSRn [ label ] MOVWI FSRn++ [ label ] MOVWI FSRn-- [ label ] MOVWI k[FSRn] Operands: n [0,1]. -32 k 31 If not present, k = 0. Operation: W INDFn 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: None Mode Syntax Preincrement ++FSRn Predecrement --FSRn Postincrement FSRn++ Postdecrement FSRn-- 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. The increment/decrement operation on FSRn WILL NOT affect any Status bits. NOP No Operation Syntax: [ label ] NOP Operands: None Operation: No operation Status Affected: None Description: No operation. Words: 1 Cycles: 1 Example: NOP OPTION Load OPTION_REG Register with W Syntax: [ label ] OPTION Operands: None Operation: (W) OPTION_REG Status Affected: None Description: Move data from W register to OPTION_REG register. RESET Software Reset Syntax: [ label ] RESET Operands: None Operation: Execute a device Reset. Resets the nRI flag of the PCON register. Status Affected: None Description: This instruction provides a way to execute a hardware Reset by soft- ware. |
