2.1
The Modem Analog Front End (MAFE) Interface is a serial port integrated into the 73M1903C device to
interface to a host controller or a DSP. This serial data port is a bi-directional port that is supported by
most DSPs available in the market.
The MAFE interface requires one end to act as a master and the other as a slave. The 73M1903C device
can be configured either as a master or as a slave (refer to
also be daisy chained in a single master and multiple slave configuration (refer to
