Divide Formatted (DIVF)
Divide Formatted is a 16-bit instruction that divides the BCD
value in the accumuator 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.
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
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP70 On anytime the value in the accumulator is negative.
SP75 On when a BCD instruction is executed and a NON-BCD number was encountered.
