MSX-E1701: Incremental counter

Quadruple mode

In the quadruple mode with each falling and rising edge of track A and track B of
the incremental signal is counted.

Direct mode

In the direct mode with each falling edge of input A is counted, whereas input B
serves as gate input. It is counted only as long as input B is on the high level.
Furthermore, in the direct mode the counting direction can be programmed via
software.

8.3.2 Hysteresis function

The hysteresis function can be used in the single, double and quadruple mode. At
hysteresis „ON" the first counting pulse after a change in rotation is not evaluated.
