6 MAJOR OPERATIONAL MODES

The major operational modes are determined by the FM[2:0] framer mode bits and a few other control bits. Unused

features are powered down and the data paths are held in reset. The configuration registers of the unused features

can be written to and read from. The function of some IO pins change in different operational modes. The line

interface operational mode is determined by the LM[2:0] bits.

6.1 DS3/E3 SCT Mode

This mode is for standard operation that uses the device in the single chip transceiver mode. It utilizes the

framer/formatter as well as the transmit/receive LIU.
