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 in the
accumulator is divided by the value formed by discrete location C0–C3 using the Divide
Formatted instruction. The value in the lower four bits of the accumulator is copied to Y10–
Y13 using the Out Formatted instruction.

Discrete Bit Flags Description
SP53 On when the value of the operand is larger than the accumulator can work with.
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP70 On any time the value in the accumulator is negative.
SP75 On when a BCD instruction is executed and a NON-BCD number was encountered.

Divide Formatted (DIVF)
Divide Formatted is a 16-bit instruction that divides the BCD
value in the accumulator by the BCD value (Aaaa), a range
of discrete bits. The specified range (Kbbb) can be 1 to 16
consecutive bits. The first part of the quotient resides in the
accumulator and the remainder resides in the first stack location..
