4 / 23 page FUNCTIONAL DESCRIPTION I- I 2C BUS SPECIFICATION This is the standard I 2C protocol. The device address is ”1101000” ; the first byte is therefore Hex D0 for a write operation and Hex D1 for a read operation. I.1 - Write Operation The first byte is the device address plus the direction bit (R/W = 0). The second byte contains the internal address of the first register to be accessed. The next byte is written in the internal register. The following (if any) bytes are written in successive internal registers. The transfer lasts until stop conditions are encountered. The STV0196B acknowledges every byte transfer. I.2 - Read Operation The address of the first register to read is programmed in a write operation without data, and terminated by stop condition. Then another start is followed by the device address and R/W = 1 ; all successive bytes are now data read at successive positions starting from the initial address. The STV0196B acknowledges every byte transfer. Example : Write registers 0 to 3 with AA,BB,CC,DD Start Device Address, Write D0 ACK Internal Address ACK Data AA ACK Data BB ACK Data CC ACK Stop Read registers 2 and 3 Start Device Address, Write D0 ACK Register Address 01 ACK Stop Start Device Address, Read D1 ACK Data Read BB ACK Data Read CC ACK Stop I.3 - Identification Register This read only register gives the release number of the circuit in order to ensure software compatibility. The read value is Hex 83 for STV0196B and Hex 81 for STV0196. Internal Address : Hex 0B 1 0 0 000 11 Notes : - Unspecified register addresses must not be used. - All the unused bits in the registers must be programmed to 0. STV0196B 4/23 |
