Encode (ENCO)
The Encode instruction encodes the bit position in the
DS5 Used
accumulator having a value of 1, and returns the appropriate
HPP Used
binary representation. If the most significant bit is set to 1 (Bit
31), the Encode instruction would place the value HEX 1F
(decimal 31) in the accumulator. If the value to be encoded
is 0000 or 0001, the instruction will place a zero in the
accumulator. If the value to be encoded has more than one bit
position set to a "1", the least significant "1" will be encoded
and SP53 will be set on.
Discrete Bit Flags
SP63
SP70
NOTE: The status flags are only valid until another instruction that uses the same flags is executed.
In the following example, when X1 is on, The value in V2000 is loaded into the accumulator
using the Load instruction. The bit position set to a "1" in the accumulator is encoded to the
corresponding 5 bit binary value using the Encode instruction. The value in the lower 16 bits
of the accumulator is copied to V2010 using the Out instruction.
