17. up resistor The basic 12C bus protocol is defined as Data transfer is initiated only when the bus is not busy Changes in the data line occur when the clock is LOW and must be stable when the clock is HIGH Any changes in data lines when the clock is HIGH will be interpreted as control signals Different conditions on I2C bus The I C bus protocol defines the following conditions Not busy both SDA and SCL remain HIGH START a HIGH to LOW transition on SDA while SCL is HIGH STOP a LOW to HIGH transition on SDA while SCL is HIGH Data valid after a START condition data on SDA must be stable for the duration of the HIGH period of SCL Data transfer The master initiates each data transfer using a START condition and terminates it by generating a STOP condition To facilitate the next byte transfer each byte of data must be acknowledged by the receiver The acknowledgement is done by pulling the SDA line LOW on the ninth bit of the data An extra clock pulse needs to be generated by the master to accommodate this bit For more detailed information on the operation of the bus refer to The C bus specification I C bus address The address of the ISP1521 is given in Table 10 Table 10 12C bus slave address Value 0 0 1 1 0 1 0 0 1 Koninklijke Philips Electronics N V 2004 All rights reserved Product data Rev 03 24 November 2004 17 of 53 Philips Semiconductors ISP1 521 Hi Speed
