# Tiny Tapeout Spin Display - select-reset-reverse
Logic to spin 7 segment display.
Clock is expected to be 2hz.
Uses D flip-flops with reset to sequence like a shift register
the segments of the dislay, only for the outer 6 segements A, B, C, D, E, F
The D flip-flips feed the !Q inverted output to the start of the FF,
but this is fliped to the Q out of the first FF via a multiplexer.
The muliplexer is controled by input IN0, setting to "1" has the
affect to stop the sequence after the FF's progress 6 shifts.
Revesing is done by muliplexers switching the FF outputs to the display.
Reset clears all the display.
Input IN0 stops the sequence after its full 6 shifts.
Input IN1 reverses the sequence.
