V CC =5.5V, SDA=SCL=V CC ,VCLK=GND *1
*1 Transmit-Only Mode - After power on, the BR24C21/F/FJ/FV is in Standby mode and does not provide the clock to the VCLK pin.
After the clock is provided to VCLK, the device is switched from Standby to Transmit-Only Mode, and the operating current flows.
Bi-directional Mode - The BR24C21/F/FJ/FV is in Standby mode after each command is performed.
