81 / 170 page  81/170 uPSD3234A, uPSD3234BV, uPSD3233B, uPSD3233BV DDC2B Protocol DDC2B is constructed based on the Philips I2C in- terface. However, in the level of DDC2B, PC host is fixed as the master and the monitor is always re- garded as the slave. Both master and slave can be operated as a transmitter or receiver, but the mas- ter device determines which mode is activated. In this protocol, address pointer is also used. According to DDC2B specification, A0 (for WRITE Mode) and A1 (for READ Mode) are assigned as the default address of monitors. The reception of the incoming data in WRITE Mode or the updating of the outgoing data in READ Mode should be finished within the speci- fied time limit. If software in the slave’s side cannot react to the master in time, based on I2C protocol, SCL pin can be stretched low to inhibit the further action from the master. The transaction can be proceeded in either byte or burst format. Figure 43.
