When SCLK stops in “L” level When SCLK stops in “H” level Data length : 24bits Clock frequency : 5MHz or less When 24 SCLK clock signals have been input during the high period of SDEN, the SDATA is taken in at the rising edge of SCLK. Note: If the number of SCLK clock signals during the high period of SDEN is 23 or less, SDATA is not taken in. If it is 25 or more, the register address is automatically incremented every time 1byte is taken in. Data organization The slave address is assigned by the first byte, and the register address on the serial map is specified by the next byte. The third byte transfers the data to the address specified by the register address that was written by the second byte and if the data subsequently continues even after this, the register address is automatically incremented for the fourth and subsequent bytes. As a result, it is possible to send the data continuously from the specified addresses. Data of less than one byte is ignored. However, when the address reaches 0fh, the next byte to be transferred becomes 00h. www.onsemi.com 9 LV5237JA Serial data transfer example (slave address=0000 001-) When I set register address 02h and write in data (the smallest data length) When I set register address 02h and write in data for 3 bytes When I set register address 02h and write in data for 3 byte, and following data is less than a signal byte When slave address does not accord SDEN SDATA 0 0 0 0 1 0 0 - Slave address Ignore the last data www.onsemi.com 10 LV5237JA 3) 2-wire serial bus transfer formats LV5237JA receives the command by communication format by 2 line type serial communication of SCLK, SDATA.

Note: When SCLK is less than 27th clock track, and BLANK is different from communication format such as “1”, after start detection, do not take in SDATA. When SCLK is higher than 28th clock track, start detection is confirmed, or it is automatic, and register address is incremented every 1byte (8bit) + BLANK (“0”) unless BLANL is “1”.

After start detection, the first single byte (8bit) is assigned to slave address, and a write store of the slave address completes it in BLANK”0”. The next single byte appoints register address in the serial manufacturing auto protocol, and a write of the register address is completed in BLANK”0”. The third byte performs a data transfer to the address which it appointed in the register address which it wrote in at the second byte and it complete data transfer in BLANK”0” and write in it. When data continues after this, register address is automatically incremented after the fourth byte and a data transfer is completed each time and, in BLANK”0”, writes in it. Data Forward continuous from designated register address is enabled, but, as for the redirecting address of the next byte, it is in this way with for “00h” when register address becomes “0fh”. In addition, when serial data uptake BLANK is “1”, including slave address selection and register address assignment, the single byte data just before it is ignored without being written in, and the subsequent data is ignored until it is detected a start. www.onsemi.com 11 LV5237JA Serial data transfer example (slave address=0000 001-) When I set register address 02h and write in data (the smallest data length) When I set register address 02h and write in data for 3 bytes When I set register address 02h and write in data for 1 byte, and BLANK after the following byte in the case of “1” When I set register address 02h, but BLANK after the byte in the case of “1” When slave address does not accord SDATA continues more than 10bit; and in the case of 1 "" (start detection of this case)
