17.2.4.4 Packet Timeout

When a master sends an I²C packet, there is no way of being sure that a slave will acknowledge the packet. To avoid stalling the device forever while waiting for an acknowledge, a user selectable timeout is provided in the i2c_master_config struct which lets the driver exit a read or write operation after the specified time. The function will then return the STATUS_ERR_TIMEOUT flag.

This is also the case for the slave when using the functions postfixed _wait.

The time before the timeout occurs, will be the same as for unknown bus state timeout.
