Manufacturer:ST Description:The READ ROM command sequence is the fastest sequence that allows the host to read the 8-bit family code and 48-bit identification number. It is used if only one SDQ slave device is attached to the bus. The READ ROM sequence starts with the host generating the RESET pulse of at least 480 µs. The bq2022 responds with a PRESENCE pulse. Next, the host continues by issuing the READ ROM command, 33h, and then reads the ROM and CRC byte using the READ signaling (see the READ and WRITE signals section) during the data frame. |
