Multi-Master IIC Interface (MMIIC)
14.3 I/O Pins
The MMIIC module uses two I/O pins, shared with standard port I/O pins. The full name of the MMIIC I/O
pins are listed in
The SDA and SDL pins are open-drain. When configured as general purpose output pins (PTB0 and
PTB1), pullup resistors must be connected to these pins.
14.4 Multi-Master IIC System Configuration
The multi-master IIC system uses a serial data line SDA and a serial clock line SCL for data transfer. All
devices connected to it must have open collector (drain) outputs and the logical-AND function is
performed on both lines by two pull-up resistors.
