Device configuration

Doc ID 022817 Rev 2

19/65

When the I2C microcontroller cell is disabled, the SDA and SCL ports revert to being

standard I/O port pins.

On the L6360, the SDA output is an open drain pin.

Mode selection

Possible data transfer formats are:

●

The master transmitter transmits to the slave receiver. The transfer direction is not

changed (see Figure 5).

●

The slave receiver acknowledges each byte.

●

The master reads data from the slave immediately after the first byte (see Figure 6). At

the moment of the first acknowledge, the master transmitter becomes a master receiver

and the slave receiver becomes a slave transmitter.

This first acknowledge is still generated by the slave.

Subsequent acknowledges are generated by the master. The STOP condition is generated

by the master which sends a not-acknowledge (A) just prior to the STOP condition.
