Technical Summary
The MC68QH302, quad HDLC integrated multiprotocol processor, is based on the three-
SCC 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.
