Microchip Technology 

PIC16(L)F1512/3

The I2C interface supports the following modes and

features:

• Master mode

• Slave mode

• Byte NACKing (Slave mode)

• Limited Multi-master support

• 7-bit and 10-bit addressing

• Start and Stop interrupts

• Interrupt masking

• Clock stretching

• Bus collision detection

• General call address matching

• Address masking

• Address Hold and Data Hold modes

• Selectable SDA hold times

Figure 20-2 is a block diagram of the I2C interface

module in Master mode. Figure 20-3 is a diagram of the

I2C interface module in Slave mode.
