PIC16C72

Each PIC16CXXX  family  instruction is a 14-bit word divided into an OPCODE which specifies the instruction type and one or more operands which further specify the operation of the instruction. The PIC16CXXX family instruction set summary in Table 11-2 lists byteoriented, bit-oriented, and literal and control operations. Table 11-1 shows the opcode field descriptions.

For byte-oriented instructions, 'f' represents a file register designator and 'd' represents a destination designator. The file register designator specifies which file register is to be used by the instruction.

The destination designator specifies where the result of the operation is to be placed. If 'd' is zero, the result is placed in the W register. If 'd' is one, the result is placed in the file register specified in the instruction.

For bit-oriented instructions, 'b' represents a bit field designator which selects the number of the bit affected by the operation, while 'f' represents the number of the file in which the bit is located.

For  literal and control operations, 'k' represents an eight or eleven bit constant or literal value.
