NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X6 is on, the BCD value formed by discrete locations
X0–X3 is loaded into the accumulator using the LDF instruction. The BCD value formed
by discrete locations C0–C3 is added to the value in the accumulator using the ADDF
instruction. The value in the lower four bits of the accumulator is copied to Y10–Y13 using
the OUTF instruction.

Discrete Bit Flags Description
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP66 On when the 16-bit addition instruction results in a carry.
SP67 On when the 32 bit addition instruction results in a carry.
SP70 On anytime the value in the accumulator is negative.
SP73 On when a signed addition or subtraction results in an incorrect sign bit.
SP75 On when a BCD instruction is executed and a NON-BCD number was encountered.

Add Formatted (ADDF)
Add Formatted is a 32-bit instruction that adds the BCD value
in the accumulator with the BCD value (Aaaa) which is a range
of discrete bits. The specified range (Kbbb) can be 1 to 32
consecutive bits. The result resides in the accumulator.
