71 / 170 page  71/170 uPSD3234A, uPSD3234BV, uPSD3233B, uPSD3233BV I2C INTERFACE There are two serial I2C ports implemented in the uPSD323X Devices. The serial port supports the twin line I2C-bus, con- sists of a data line (SDAx) and a clock line (SCLx). Depending on the configuration, the SDA and SCL lines may require pull-up resistors. ■ SDA1, SCL1: the serial port line for DDC Protocol ■ SDA2, SCL2: the serial port line for general I2C bus connection In both I2C interfaces, these lines also function as I/O port lines as follows. ■ SDA1 / P4.0, SCL1 / P4.1, SDA2 / P3.6, SCL2 / P3.7 The system is unique because data transport, clock generation, address recognition and bus control arbitration are all controlled by hardware. The I2C serial I/O has complete autonomy in byte handling and operates in 4 modes. ■ Master transmitter ■ Master receiver ■ Slave transmitter ■ Slave receiver These functions are controlled by the SFRs. ■ SxCON: the control of byte handling and the operation of 4 mode. ■ SxSTA: the contents of its register may also be used as a vector to various service routines. ■ SxDAT: data shift register. ■ SxADR: slave address register. Slave address recognition is performed by On-Chip H/W. Figure 39. Block Diagram of the I2C Bus Serial I/O Table 50.
