PIC16C72

1. Voltage spikes below VSS at the MCLR pin, inducing currents greater than 80 mA, may cause latch-up. Thus, a series resistor of 50-100Ω should be used when applying a "low" level to the MCLR pin rather than pulling this pin directly to V_SS.
2. Power dissipation is calculated as follows: Pdis = V_DD x {I_DD - I_OH} + {(V_DD - V_OH) x I_OH} + (V_Ol x I_OL).

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.
