HPC46400E
Description
The HPC46400E is an upgraded HPC16400 Features have been added to support V 120 the 8-bit mode has been enhanced to support all instructions and the UART has been changed to provide more flexibility and power The HPC46400E is fully upward patible with the HPC16400 The HPC46400E has 4 functional blocks to support a wide range of munication application-2 HDLC channels 4 channel DMA controller to facilitate data flow for the HDLC channels programmable serial interface and UART The serial interface decoder allows the 2 HDLC channels to be used with devices using interchip serial link for point-topoint and multipoint data exchanges The decoder generates enable signals for the HDLC channels allowing multiplexed D and B channel data to be accessed The HDLC channels manage the link by providing sequencing using the HDLC framing along with error control based upon a cyclic redundancy check (CRC) Multiple address recognition modes and both bit and byte modes of operation are...
