The first byte of data transferred by the device after a start bit is the slave address. The JN5139 supports both 7-bit
and 10-bit slave addresses by generating either one or two address transfers. Only the slave with a matching
address will respond by returning an acknowledge bit.
14.1 Connecting Devices
The clock and data lines, SIF_D and SIF_CLK, are alternative functions of DIO lines 15 and 14 respectively. The
serial interface function of these pins is selected when the interface is enabled. They are both bi-directional lines,
connected internally to the positive supply voltage via weak (45k Ω ) programmable pull-up resistors. However, it is
recommended that external 4.7k Ω pull-ups be used for reliable operation at high bus speeds, as shown in Figure 36.
When the bus is free, both lines are HIGH. The output stages of devices connected to the bus must have an open-
drain or open-collector in order to perform the wired-AND function. The number of devices connected to the bus is
solely dependent on the bus capacitance limit of 400pF.

14.2 Clock Stretching
Slave devices can use clock stretching to slow down the transfer bit rate. After the master has driven SIF_CLK low,
the slave can drive SIF_CLK low for the required period and then release it. If the slave’s SIF_CLK low period is
greater than the master’s low period, the resulting SIF_CLK bus signal low period is stretched thus inserting wait
states.
