6.21.6 Electrical specification

6.22 TWIM — I2C compatible two-wire interface master

with EasyDMA

TWI master with EasyDMA (TWIM) is a two-wire half-duplex master which can communicate with multiple

slave devices connected to the same bus.

Listed here are the main features for TWIM:

• I2C compatible

• Supported baud rates: 100, 250, 400 kbps

• Support for clock stretching (non I2C compliant)

• EasyDMA

The two-wire interface can communicate with a bi-directional wired-AND bus with two lines (SCL, SDA).

The protocol makes it possible to interconnect up to 127 individually addressable devices. TWIM is not

compatible with CBUS.

The GPIOs used for each two-wire interface line can be chosen from any GPIO on the device and are

independently configurable. This enables great flexibility in device pinout and efficient use of board space

and signal routing.
