Manufacturer:BOURNS Description:The SEARCH ROM command, F0h, is used to obtain the 8-bit family code and the 48-bit identification number and 8-bit CRC of any SDQ device when it is unknown. All devices on the bus are read under the SEARCH ROM command with the use of a collision-detect and device-decode method. Figure 5 shows the SEARCH ROM sequence started by the host, generating the RESET pulse of at least 480 µs. The bq2022 responds with a PRESENCE pulse. The host then issues the command in the command frame by writing an F0h. During the DATA READ of the SEARCH ROM sequence, each bit is transmitted three times. The bq2022 transmits the bit followed by the complement of the bit. The host in turn retransmits the bit just read. Collision detection if |
