I2C

Report or set Inter-Integrated Circuit parameters. For more

information, consult the TMS320x280x Inter-Integrated Circuit

Module Reference G uide, Literature Number: SPR U721A,

available on the Texas Instruments Web site.

Mode

Conﬁgure the I2C module as

Master or Slave.

If a module is an I2C master, it:

• Initiates communication with slave nodes by sending the

slave address and requesting data transfer to or fro m the

slave.

• Outputs the Mas t er clock frequ ency on the serial clock

line (SCL) line.

If a module is an I2C slave, it:

• Synchronizes itself with the serial clock line (SCL) line.

• Responds to communication requests from the master.

When Mode is

Slave, y ou can conﬁgure the Add ressing

format, Address register,andBit count parameters.
