ABSTRACT:
A matrix of routing cells forming a cross-bar decoder (310). Signal triplets are coupled through the cross-bar decoder (310) based on control by a microprocessor. A register (50) provide control signals to the cross-bar decoder (310) to either activate or deactivate routing of the triplet signals through cells of the cross-bar decoder (310). The routing cells are arranged in a matrix of columns and rows. Each row of cells is associated with a common data signal input, and each column of the matrix is associated with a common I/O pin. The cells are individually enabled by the microprocessor so that any data signal can be coupled to any of the I/O pins. In addition to routing data signals through the cells, other signals are also routed through the cells.
