Intel® LPSS Inter-Integrated Circuit (I2C) Controllers
The PCH implements six I2C controllers for six independent I2C interfaces, I2C0-I2C5. Each interface is a two-wire serial interface consisting of a serial data line (SDA) and a serial clock (SCL).
I2C4 and I2C5 only implement the I2C host controllers and do not incorporate a DMA controller. Therefore, I2C4 and I2C5 are restricted to operate in PIO mode only.
The I2C interfaces support the following features:
- Speed: standard mode (up to 100 Kb/s), fast mode (up to 400 Kb/s), fast mode plus (up to 1 MB/s) and High speed mode (up to 3.2 Mb/s).
- 1.8 V or 3.3 V support (depending on the voltage supplied to the I2C signal group)
- Master I2C operation only
- 7-bit or 10-bit addressing
- 7-bit or 10-bit combined format transfers
- Bulk transmit mode
- Ignoring CBUS addresses (an older ancestor of I2C used to share the I2C bus)
- Interrupt or polled-mode operation
- Bit and byte waiting at all bus speed
- Component parameters for configurable software driver support
- Programmable SDA hold time (tHD; DAT)
- DMA support with 64-byte DMA FIFO per channel (up to 32-byte burst)
- 64-byte Tx FIFO and 64-byte Rx FIFO
- SW controlled serial data line (SDA) and serial clock (SCL)
