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 SDAx hold times

Figure 25-2 is a block diagram of the I2C interface

module in Master mode. Figure 25-3 is a diagram of the

I2C interface module in Slave mode.

The PIC16F1827 has two MSSP modules, MSSP1 and

MSSP2, each module operating independently from

the other.

MSSPx BLOCK DIAGRAM (I2C™ MASTER MODE)

Note 1: In devices with more than one MSSP

module, it is very important to pay close

attention to SSPxCONx register names.

SSP1CON1 and SSP1CON2 registers

control different operational aspects of

the same module, while SSP1CON1 and

SSP2CON1 control the same features for

two different modules.

2: Throughout this section, generic refer-

ences to an MSSP module in any of its

operating modes may be interpreted as

being equally applicable to MSSP1 or

MSSP2. Register names, module I/O

signals, and bit names may use the

generic designator ‘x’ to indicate the use

of a numeral to distinguish a particular

module when required.
