The CCR is the LSB of the processor status register (SR). Bits 4–0 act as indicator flags for results
generated by processor operations. The extend bit (X) is also an input operand during multiprecision
arithmetic computations. The CCR register must be explicitly loaded after reset and before any compare
(CMP), Bcc, or Scc instructions are executed.

Extend condition code bit. Set to the C-bit value for arithmetic operations; otherwise not affected or set to a specified
result.
Negative condition code bit. Set if most significant bit of the result is set; otherwise cleared.
Zero condition code bit. Set if result equals zero; otherwise cleared.
Overflow condition code bit. Set if an arithmetic overflow occurs implying the result cannot be represented in operand
size; otherwise cleared.
Carry condition code bit. Set if a carry out of the operand msb occurs for an addition or if a borrow occurs in a
subtraction; otherwise cleared.
