Control and register interfaces

TWI — Two-Wire Interface

TWI is the main interface to control and monitor the device state through registers.

The following are the TWI main features:
  • I2C compatible
  • TWI clock 100 kHz - 400 kHz supported
  • Slave device with 7-bit slave address
  • Clock stretching not supported
  • General Call address not supported
  • Software Reset not supported
  • Device ID not supported

TWI slave address

The TWI 7-bit slave-address value is 1110000b = 0x70h.
