`BITS [0x2000], 3` - Set bit `3` in memory at address `0x2000`
- Reads a memory address as an argument.
- Reads a bit index from the next byte.
- Ensures the bit index is between `0-7`.
- Sets the specified bit in the memory address.
- Increments the program counter.
### **BITC_ADDR**
`BITC [0x2000], 5` - Clear bit `5` in memory at address `0x2000`
- Reads a memory address as an argument.
- Reads a bit index from the next byte.
- Ensures the bit index is between `0-7`.
- Clears the specified bit in the memory address.
- Increments the program counter.
### **BITS_RN**
`BITS R1, 2` - Set bit `2` in register `R1`
- Reads a register number.
- Reads a bit index from the next byte.
- Ensures the register is valid (`0 - REG_COUNT - 1`).
- Ensures the bit index is between `0-7`.
- Sets the specified bit in the register.
- Increments the program counter.
### **BITC_RN**
`BITC R2, 6` - Clear bit `6` in register `R2`
- Reads a register number.
- Reads a bit index from the next byte.
- Ensures the register is valid (`0 - REG_COUNT - 1`).
- Ensures the bit index is between `0-7`.
- Clears the specified bit in the register.
- Increments the program counter.
### **BITS (Special Instruction)**
- This mnemonic decides between `BITS_RN` and `BITS_ADDR` based on the operand.
- If the operand is a register, `BITS_RN` is used.
- If the operand is a memory address, `BITS_ADDR` is used.
### **BITC (Special Instruction)**
- This mnemonic decides between `BITC_RN` and `BITC_ADDR` based on the operand.
- If the operand is a register, `BITC_RN` is used.
- If the operand is a memory address, `BITC_ADDR` is used.
`BITC R2, 6` - Clear bit `6` in register `R2`
