OMAP5912 Description

MCSI1 Interface

FSYNCH_OUT_Z

Introduction

The MCSI1 is a multichannel serial interface, half-duplex, master/slave.

MCSI1 can be used in OMAP5912 to interface the Bluetooth voice module.

In this case, the interface is an 8-kHz frame serial port, 8-bit data transfer. It

is a 4-wire interface with a bidirectional serial clock and frame synchronization.

If the Bluetooth baseband device is not synchronous with the modem network,

the Bluetooth voice interface receives the clock and frame synchronization

from OMAP5912 MCSI1.
