  	 - The SP must always be greater than the DP. If not, the CPU will recognize that the Stack and Data have collided and will halt.
 
  - The Status register is an 8 bit register whose various bits are used as flags. Only three of these flags are used in the current implementation.
-	 - Bit 0 is the Carry/Borrow Flag. Any arithmetic operation either sets or clears it depending on whether or not the result causes Q to overflow/underflow. It is a 1 if a carry/underflow occurred, and a 0 otherwise.
+	 - Bit 0 is the Carry/Borrow Flag. Any arithmetic operation either sets or clears it depending on whether or not the result causes Q to overflow/underflow. It is a 1 if a carry/underflow occurred, and a 0 otherwise. If A or B overflows or underflows from the use of an increment or decrement instruction, this flag will also be set. Non-overflowing increments or decrements will also reset it.
 	 - Bit 1 is the Stack Collision Flag. It is set if the Data Pointer's value ever meets or exceeds the Stack Pointer's value. This condition also sets the Halt Flag.
 	 - Bit 7 is the Halt Flag. It is set by the HALT instruction, or if there is a stack collision.
