185 / 268 page  185/268 - SERIAL PERIPHERAL INTERFACE (SPI) SERIAL PERIPHERAL INTERFACE (Cont’d) 8.10.5 Working With Other Protocols The SPI peripheral offers the following facilities for operation with S-bus/I2C-bus and IM-bus proto- cols: s Interrupt request on start/stop detection s Hardware clock synchronisation s Arbitration lost flag with an automatic set of data line Note that the I/O bit associated with the SPI should be returned to a defined state as a normal I/O pin before changing the SPI protocol. The following paragraphs provide information on how to manage these protocols. 8.10.6 I2C-bus Interface The I2C-bus is a two-wire bidirectional data-bus, the two lines being SDA (Serial DAta) and SCL (Serial CLock). Both are open drain lines, to allow arbitration. As shown in Figure 75, data is toggled with clock low. An I²C bus start condition is the transition on SDI from 1 to 0 with the SCK held high. In a stop condition, the SCK is also high and the transition on SDI is from 0 to 1. During both of these conditions, if SPEN = 0 and BMS = 1 then an interrupt request is performed. Each transmission consists of nine clock pulses (SCL line). The first 8 pulses transmit the byte (MSB first), the ninth pulse is used by the receiver to acknowledge. Figure 74.
