Each register contains one of the numeric values that encode the interaction of one of the inputs with one of the outputs. | Each register contains one of the numeric values that encode the interaction of one of the inputs with one of the outputs. | ||
The rows describe the actions when the corresponding input is changed, the columns describe the corresponding outputs. | |||
Therefore, the cell at the intersection of the entry date and the exit column contains a value that specifies the operation of the exit when the corresponding entry is changed. | |||
The action is described by the value of the lower four bits of the hex word '''0b0000 0000 0000 yyxx''' stored in the register. | |||
The '''yy''' bits describe the changing of input value from 0 to 1 (front), and the '''xx''' bits describe the changing from 1 to 0 (back). | |||
