…
After the power is on, the BR24C21, BR24C21F, BR24C21FJ and BR24C21FV are in Standby state without providing the clock on the VCLK pin.
After the VCLK pin is provided the clock, the device is switched from Standby to Transmit-Only Mode, and the operating current runs.
Bi-directional Mode
…
The BR24C21, BR24C21F, BR24C21FJ and BR24C21FV are in Standby state after each command is porformed.
