addition operation produces a carry out of bit 7 of the accumulator or when a subtraction operation
requires a borrow. Some logical operations and data manipulation instructions also clear or set the
carry/borrow bit (as in bit test and branch instructions and shifts and rotates).

five bits that indicate the results of the instruction just executed.
synchronize the machine and direct various operations. The control unit decodes instructions and
generates the internal control signals that perform the requested operations. The outputs of the
control unit drive the execution unit, which contains the arithmetic logic unit (ALU), CPU registers, and
bus interface.
frequency is equal to the frequency of the oscillator output, CGMXCLK, divided by four.
