Segment (SEG)
The BCD / Segment instruction converts a four digit HEX
value in the accumulator to seven segment display format.
The result resides in the accumulator.
In the following example, when X1 is on, the value in V1400 is loaded into the lower 16 bits
of the accumulator using the Load instruction. The binary (HEX) value in the accumulator is
converted to seven segment format using the Segment instruction. The bit pattern in the
accumulator is copied to Y20–Y57 using the Out Formatted instruction.
