246 / 322 page ![]() PIC18FXX39 DS30485A-page 244 Preliminary 2002 Microchip Technology Inc. RLNCF Rotate Left f (no carry) Syntax: [ label ] RLNCF f [,d [,a] Operands: 0 ≤ f ≤ 255 d ∈ [0,1] a ∈ [0,1] Operation: (f<n>) → dest<n+1>, (f<7>) → dest<0> Status Affected: N, Z Encoding: 0100 01da ffff ffff Description: The contents of register 'f' are rotated one bit to the left. If 'd' is 0, the result is placed in W. If 'd' is 1, the result is stored back in register 'f' (default). If ‘a’ is 0, the Access Bank will be selected, overriding the BSR value. If ‘a’ is 1, then the bank will be selected as per the BSR value (default). Words: 1 Cycles: 1 Q Cycle Activity: Q1 Q2 Q3 Q4 Decode Read register 'f' Process Data Write to destination Example: RLNCF REG, 1, 0 Before Instruction REG = 1010 1011 After Instruction REG = 0101 0111 register f RRCF Rotate Right f through Carry Syntax: [ label ] RRCF f [,d [,a] Operands: 0 ≤ f ≤ 255 d ∈ [0,1] a ∈ [0,1] Operation: (f<n>) → dest<n-1>, (f<0>) → C, (C) → dest<7> Status Affected: C, N, Z Encoding: 0011 00da ffff ffff Description: The contents of register 'f' are rotated one bit to the right through the Carry Flag. If 'd' is 0, the result is placed in W. If 'd' is 1, the result is placed back in register 'f' (default). If ‘a’ is 0, the Access Bank will be selected, overriding the BSR value. If ‘a’ is 1, then the bank will be selected as per the BSR value (default). Words: 1 Cycles: 1 Q Cycle Activity: Q1 Q2 Q3 Q4 Decode Read register 'f' Process Data Write to destination Example: RRCF REG, 0, 0 Before Instruction REG = 1110 0110 C= 0 After Instruction REG = 1110 0110 W= 0111 0011 C= 0 C register f |
