Multiply Formatted (MULF)
Multiply Formatted is a 16-bit instruction that multiplies the
BCD value in the accumulator by the BCD value (Aaaa)
which is a range of discrete bits. The specified range (Kbbb)
can be 1 to 16 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 multiplied by the value in the accumulator using the Multiply
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.
