8.24 I2C

The inter-integrated circuit interface (I2C) peripherals in these devices provide bidirectional data transfer with other I2C devices on the bus and support the following key features:

  • 7-bit and 10-bit addressing mode with multiple 7-bit target addresses
  • Multiple-controller transmitter or receiver mode
  • Target receiver or transmitter mode with configurable clock stretching
  • Support Standard-mode (Sm), with a bit rate up to 100kbps
  • Support Fast-mode (Fm), with a bit rate up to 400kbps
  • Support Fast-mode Plus (Fm+), with a bit rate up to 1Mbps
  • Separated transmit and receive FIFOs support DMA data transfer
  • Support SMBus 3.0 with PEC, ARP, timeout detection and host support
  • Wakeup from low power mode on address match
  • Support analog and digital glitch filter for input signal glitch suppression

For more details, see the I2C chapter of the MSPM0 L-Series 32MHz Microcontrollers Technical Reference Manual.
