The Load Formatted instruction loads
1--32 consecutive bits from discrete
memory locations into 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.

Discrete Bit Flags Description
SP76 on when the value loaded into the accumulator by any instruction is 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.
