eral or microcontroller devices. These peripheral
devices may be serial EEPROMs, display drivers, A/D
Converters, etc.

• 7-bit and 10-bit device addresses
• General call address, as defined in the I
• Clock stretching to provide delays for the
• Both 100 kHz and 400 kHz bus specifications.
• Configurable address masking
• Multi-Master modes to prevent loss of messages
• Bus Repeater mode, allowing the acceptance of
• Automatic SCL

The I
cannot be reassigned to alternate pins using peripheral
pin select. To allow some flexibility with peripheral
multiplexing, the I2C1 module in all devices, can be
reassigned to the alternate pins, designated as ASCL1
and ASDA1 during device configuration.
Pin assignment is controlled by the I2C1SEL Configu-
ration bit; programming this bit (= 0) multiplexes the
module to the ASCL1 and ASDA1 pins.
