7.2 Internal flags
The Standby mode is the first-level power saving mode of the transceiver, offering reduced
current consumption. In Standby mode the transceiver is not able to transmit or receive
data and the low-power receiver is activated to monitor bus activity. The bus pins are
biased at ground level (via R

The Go-to-sleep command mode is the controlled route for entering Sleep mode. In
