Load Formatted (LDF)
The Load Formatted instruction loads 1–32
DS5 Used
consecutive bits from discrete memory locations into
HPP Used
the accumulator. The instruction requires a starting
location (Aaaa) and the number of bits (Kbbb) to be
loaded. Unused accumulator bit locations are set to zero.

NOTE: Two consecutive Load instructions will place the value of the first load instruction onto the
accumulator stack.
In the following example, when C0 is on, the binary pattern of C10–C16 (7 bits) will be
loaded into the accumulator using the Load Formatted instruction. The lower 7 bits of the
accumulator are output to Y0–Y6 using the Out Formatted instruction.
