The module uses the INTEL 8273 HDLC/SDLC controller chip as described in appendix 1. The module is flexible and allows either DMA or non-DMA data transfers, interrupt or non-interrupt driven. If DMA tranfers are used, an ID-7009 DMA priority module must be present. The ID-7047 uses separate channels for input and output. If interrupt driven I/O is used an ID-7003 Interrupt Priority module must be present. *END*
