PRODUCTION DATA
The device contains one I2C Serial Port. Figure 9-34 shows how the I2C peripheral module interfaces within the device.
The I2C module has the following features:
For more information on the I2C, see the Inter-Integrated Circuit Module (I2C) chapter in the TMS320F2802x,TMS320F2802xx Technical Reference Manual.
The registers in Table 9-26 configure and control the I2C port operation.
