The LPI2C slave does not implement a timeout due to SCL and/or SDA being stuck low.
If this detection is required, the LPI2C master logic should be used and software can reset
the LPI2C slave when this condition is detected.
47.4.4 Interrupts and DMA Requests
The LPI2C master and slave interrupts may be combined depending on the device.
The LPI2C master and slave transmit DMA requests may be combined depending on the
device.
The LPI2C master and slave receive DMA requests may be combined depending on the
device.
47.4.4.1 Master mode
The following table illustrates the master mode sources that can generate the LPI2C
master interrupt and LPI2C master transmit/receive DMA requests.
