Standby mode is a low power mode where the driver and receiver are disabled, reducing current consumption. However, this is not the lowest power mode of the device since the INH terminal is on, allowing the rest of the system to resume normal operation.

During standby mode, a wake up request (WAKERQ) is indicated by the RXD terminal being low. The wake up source is identified via the nFAULT pin after the device is returned to normal mode.
