1MHz+ Quadrature Divider for attiny13

Quadrature divider board. Actual size: .7x.4 inches (about 18x10mm)

This untested code, along with an Eagle schematic and board layout, are for a quadrature divider that polls at over 1MHz. The R and S test points are used to program the device.

Like the 400kHz triple divider, this program uses a state table generated by "mkstate.py", and is GPL software.

For real-world use, external pull-ups should probably be added to the board's input side, according to the directions of the encoder manufacturer.
