This feature is used for both online and offline testing. The contents of the Output Data Registers may be read at anytime, thereby supporting online testing. The outputs may be put into offline test mode by setting a bit in the CSR. In the offline test mode, the open- collector outputs are all disabled. Data patterns may then be written to and read from the Output Registers for test purposes without affecting the outputs. On powerup or reset, the board is placed in the test mode. Output Data Registers should be initialized prior to being put online to avoid undetermined states.
