21   Two Wire serial Interface (TWI0/ I2C0) 

The  Two-Wire  serial  Interface  is  a  two-wire,  bi-directional  serial  bus.  It  is  ideally  suited  for  typical 

microcontroller applications. 

 
The TWI/ I2C protocol allows the systems designer to interconnect up to 128 different devices using only 

two bi-directional bus lines, one for clock (TWI0_SCL) and one for data (TWI0_SDA). The TWI bus provides 
control of TWI0_SDA (serial data), TWI0_SCL (serial clock) generation and synchronization, arbitration logic, 
and  START/STOP  control  and  generation.  The  only  external  hardware  needed  to  implement  this  bus  is  a 
single  pull-up  resistor  for  each  of  the  TWI  bus  lines.  All  devices  connected  to  the  bus  have  individual 
addresses, and mechanisms for resolving bus contention are inherent in the TWI/ I2C protocol.

The  TWI/  I2C  bus  may  operate  as  a  master  and/or  slave,  and  may  function  on  a  bus  with  multiple 

masters.  The  CPU  interfaces  to  the  TWI/  I2C  through  the  following  four  special  function  registers:  SICON 
configures  the  TWI/  I2C  bus;  SISTA  reports  the  status  code  of  the  TWI/  I2C  bus;  and  SIDAT  is  the  data 
register, used for both transmitting and receiving TWI/ I2C data. SIADR is the slave address register. And, the 
TWI/ I2C hardware interfaces to the serial bus via two lines: SDA (serial data line) and SCL (serial clock line).

  Operating Modes 

There are four operating modes for the TWI/ I2C:
