U4930B telefunken semiconductors rev. a1, 28-jan-97 preliminary information 4 (26) i 2 cbus specification the i 2 c-bus is a bi-directional, two-wire bus for inter- communication between the microcontroller and the ic. the transmission is done over a serial data line (sda) and synchronized by a serial clock line (scl). both lines are low activ. each transmission must begin with a start condition and end with a stop condition . between a start and a stop condition, when scl is high, the data line sda must be stable. only while scl is low is the data line allowed to change. each transmission consists of at least three bytes. each byte has to be followed immediately by an acknowledge bit aao. the maximum clock frequency is 100 khz. ttl level (high > 3 v, low < 1.5 v) is used for driving. the module address for the U4930B is abao hex or a1011 1010o 2 in the write mode. the ic differentiates between normal and autoincrement mode transmission. for the autoincrement mode, set the sixth bit of the subaddress byte to a1o. in the autoincrement mode, the subaddress can be followed by more than one byte. the bytes from the third byte on will all be interpreted as data. the subaddress will be internally automatically incremented and the ic stores the data successively in the correct registers. by programming the read/write bit a1o lsb in the module address byte the ic provides information about its internal status. when pod is read out for the first time, this bit is a1o. all other read out result in a0o until the next power down / up process occurs. ?? ?? a lsb ?? ?? a ?? ?? 0 ?? ?? x ? ? x ?? ?? a module address subaddress data byte start stop 1. normal mode ?? a ?? 0 ?? a ?? 1 ?? x ? x ?? a module address subaddress a data byte 1 start ?? ?? a ?? ?? a data byte a + 1 data byte n stop . . . 2. autoincrement mode ?? ?? a module address readable data byte start read mode (module address is a1011 1011o 2) : 95 10854 stop msb msb lsb d7 d0 write mode (module address is a1011 1010o 2) : msb lsb msb lsb d7 d0 msb lsb d7 a = acknowledge bit figure 3. i 2 c-bus transmission modes of the U4930B
