Low Power Inter-Integrated Circuit (LPI2C) Hardware Abstraction Layer.
Low Power Inter-Integrated Circuit Hardware Abstraction Layer.
LPI2C HAL provides the API for reading and writing register bit-fields belonging to the LPI2C module. It also provides an initialization function for bringing the module to the reset state.

Set the circular FIFO mode for the transmit FIFO.
This function enables or disables the circular FIFO feature of the module. When enabled, the transmit FIFO read pointer is saved to a temporary register. The transmit FIFO will be emptied as normal, but once the LPI2C master is idle and the transmit FIFO is empty, then the read pointer value will be restored from the temporary register. This will cause the contents of the transmit FIFO to be cycled through repeatedly. If AUTOSTOP is set, a STOP condition will be sent whenever the transmit FIFO is empty and the read pointer is restored.

This function enables or disables SCL clock stretching during slave-transmit address byte(s) and slave-receiver address and data byte(s) to allow software to write the Transmit ACK Register before the ACK or NACK is transmitted.

Control the conditions for setting the transmit data flag.
This function controls the conditions that will trigger transmit data events. If this option is enabled the transmit data register is automatically emptied when a slave-transmit transfer is detected. This cause the transmit data event to be triggered whenever a slave-transmit transfer is detected and negate at the end of the slave-transmit transfer. If this option is disabled the transmit data event will assert whenever the transit data register is empty and negate when the transmit data register is full. This allows the transmit data register to be filled before a slave transmit transfer is detected, but can cause the transmit data register to be written before a NACK is detected on the last byte of a slave transmit transfer.
