14 Two-Wire Serial interface
The JN5139 includes an industry standard two-wire synchronous serial interface (SIF) that provides a simple and
efficient method of data exchange between devices. The system operates as a master only and uses a serial data
line (SIF_D) and a serial clock line (SIF_CLK) to perform bi-directional data transfers; includes the following features:

Compatible with both I 2 C and SMbus peripherals (master only mode)
Software programmable clock frequency
Clock stretching and wait state generation
Software programmable acknowledge bit
Interrupt or bit-polling driven byte-by-byte data-transfers
Bus busy detection
Support for 7 and 10 bit addressing modes

The software libraries allow full control of the underlying registers and give access to the following features.
A configurable prescale register allows the interface to be configured to operate at up to 400kbit/s. The clock
generator handles the clock stretching required by some slave devices.
The Byte Command Controller handles traffic at the byte level. It takes data from the Command Register and
translates it into sequences based on the transmission of a single byte. By setting the start, stop, read, write and
acknowledge control bits in the command register it is possible to generate read or write sequences on the bus.
The data I/O shift register contains the data associated with the current transfer. During a read operation, data is
shifted into this register from the SIF_D line. When the read is complete the byte is copied into the receive register
and can be accessed.
During a write operation the contents of the transmit register are copied into the shift register and then onto the SIF_D
line. It is possible to generate an interrupt upon the completion of a byte transmission or reception. If interrupt-driven
communication is not desired it is possible to poll the status of the interface.
