I2C MODULE
The Inter-Integrated Circuit (I2C) module provides
complete hardware support for both Slave and Multi-
Master modes of the I2C serial communication
standard, with a 16-bit interface.
This module offers the following key features:
I2C interface supporting both Master and Slave
operation.
I2C Slave mode supports 7 and 10-bit address
I2C Master mode supports 7 and 10-bit address
I2C port allows bidirectional transfers between
master and slaves.
Serial clock synchronization for I2C port can be
used as a handshake mechanism to suspend and
resume serial transfer (SCLREL control).
I2C supports Multi-Master operation; detects bus
collision and will arbitrate accordingly.
14.1
Operating Function Description
The hardware fully implements all the master and slave
functions of the I2C Standard and Fast mode
specifications, as well as 7 and 10-bit addressing.
Thus, the I2C module can operate either as a slave or
a master on an I2C bus.
14.1.1
VARIOUS I2C MODES
The following types of I2C operation are supported:
I2C Slave operation with 7 or 10-bit address
I2C Master operation with 7 or 10-bit address
14.1.2
PIN CONFIGURATION IN I2C MODE
I2C has a 2-pin interface; pin SCL is clock and pin SDA
is data.
FIGURE 14-1:
PROGRAMMER鈥橲 MODEL
14.1.3
I2C REGISTERS
I2CCON and I2CSTAT are Control and Status regis-
ters, respectively. The I2CCON register is readable and
writable. The lower 6 bits of I2CSTAT are read-only.
The remaining bits of the I2CSTAT are read/write.
I2CRSR is the shift register used for shifting data,
whereas I2CRCV is the buffer register to which data
bytes are written, or from which data bytes are read.
I2CRCV is the receive buffer, as shown in Figure 16-1.
I2CTRN is the transmit register to which bytes are writ-
ten during a transmit operation, as shown in Figure 16-2.
The I2CADD register holds the slave address. A status
bit, ADD10, indicates 10-bit Address mode. The
I2CBRG acts as the Baud Rate Generator (BRG)
reload value.
In receive operations, I2CRSR and I2CRCV together
form a double-buffered receiver. When I2CRSR
receives a complete byte, it is transferred to I2CRCV
and
an
interrupt
pulse
is
generated.
During
transmission, the I2CTRN is not double-buffered.

of dsPIC30F devices and is not intended to be a complete

peripherals, register descriptions and general device
functionality, refer to the 鈥渄sPIC30F Family Reference

first 7-bit address.
