1) BCF
BCF is a resetting command instruction used for performing reset operations for a specified bit or specified register (simply called bit clearing flag or bit clearing command). Normally BCF resets the specified bit in f registers content.
- Syntax: Label BCF f, b
- Description: Reset the specified bit of register f
- Operation: Result to f
- Operand: 0 < f < 127 and 0 < b < 7
- No. of words: 1
- No. cycles: 1
- Flags: nil
2 ) BSF
BSF is the inversing operation of BCF. This is also a bitwise operation. The BSF instruction will set the specified bit in the f register (simply called Bit Set Flag or Bit Set command).
- Syntax: Label BSF f, b
- Description: Set the specified bit of register f
- Operation: Result to f
- Operand: 0 < f < 127 and 0 < b < 7
- No. of words: 1
- No. cycles: 1
- Flags: nil
