Load Address (LDA)
The Load Address instruction is a 16-bit
instruction. It converts any octal value or address to
the HEX equivalent value and loads the HEX value
into the accumulator. This instruction is useful
when an address parameter is required since all
addresses for the DL205 system are in octal.
NOTE: Two consecutive Load instructions will place the value of the first load instruction onto the
accumulator stack.
In the following example when X1 is on, the octal number 40400 will be converted to a HEX
4100 and loaded into the accumulator using the Load Address instruction. The value in the
lower 16 bits of the accumulator is copied to V2000 using the Out instruction.
