Add Formatted (ADDF)
Add Formatted is a 32-bit instruction that adds the BCD value
230
in the accumulator with the BCD value (Aaaa) which is a range
240
of discrete bits. The specified range (Kbbb) can be 1 to 32
250-1
consecutive bits. The result resides in the accumulator.

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

On when the result of the instruction causes the value in the accumulator to be zero.
On when the 16-bit addition instruction results in a carry.
On when the 32-bit addition instruction results in a carry.
On anytime the value in the accumulator is negative.
On when a BCD instruction is executed and a NON-BCD number was encountered.
