Member Data Documentation

uchar RegisterBehaviour::depends

The bits whose value before the instruction is executed will affect the processor state after execution. So for example, in MOVLW this will be 0x0; in ANDLW this will be the bits that are non-zero in the literal; in BTFSC this will be the bit being tested (if this is the register being tested).

uchar RegisterBehaviour::indep

The bits whose value after the instruction is executed is independent of the value before execution. So for example, in MOVLW, this will be 0xff; in ANDLW this will be the bits that are zero in the literal; in BTFSC this will be 0x0.
