19.0 INTER-INTEGRATED
CIRCUIT⢠(I2Câ¢)
Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 families of devices. It is not intended
to be a comprehensive reference source.
To complement the information in this
data sheet, refer to Section 19. âInter-
Integrated
Circuitâ¢
(I2Câ¢)â
(DS70330) of the âdsPIC33E/PIC24E
Family Reference Manualâ, which is
available from the Microchip web site
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 âMemory Organizationâ in
this data sheet for device-specific register
and bit information.
The dsPIC33EPXXX(GP/MC/MU)806/810/814 and
PIC24EPXXX(GP/GU)810/814 family of devices con-
tain two Inter-Integrated Circuit (I2C) modules: I2C1
and I2C2.
The I2C module provides complete hardware support
for both Slave and Multi-Master modes of the I2C serial
communication standard, with a 16-bit interface.
The I2C module has a 2-pin interface:
⢠The SCLx pin is the clock.
⢠The SDAx pin is the data.
The I2C module offers the following key features:
⢠I2C interface supporting both Master and Slave
modes of operation.
⢠I2C Slave mode supports 7 and 10-bit addressing.
⢠I2C Master mode supports 7 and 10-bit addressing.
⢠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 arbitrates accordingly.
⢠IPMI support
⢠SMBus support
