A reconfigurable datapath (13b), which may be alternatively configured for various debug modes. These modes include a breakpoint mode (20), counter mode (30a-30c), DMA mode (40), and PSA mode (50). Each configuration uses one or more of two bitcell units: a register bitcell unit (60) and a comparator bitcell unit (70). The inputs and interconnections of these bitcell units (60, 70) determine the configuration, and hence the mode, for which they are to be used.
