| Freescale Semiconductor, Inc. MC68QH302/D (Motorola Order Number) 11/97 REV 0 MC68QH302 Freescale Semiconductor, Inc... Advance Information MC68QH302 Quad HDLC Integrated Multiprotocol Processor Technical Summary The MC68QH302, quad HDLC integrated multiprotocol processor, is based on the threeSCC MC68302 family of chips with the addition of the QH protocol and two extra serial DMA channels. The QH302 supports a total of four independent communications channels, handling two HDLC or transparent channels on SCC1; see Figure 1 for a block diagram. In non-QH mode, the QH302 can be used in standard 302 applications as well. MC68QH302 Technical Summary To locate any published errata or updates for this document, refer to the website at http://www.mot.com/netcomm.
