[1] The wake flag is set if a valid wake-up event is detected while switching to Standby mode.

[2] The wake flag is set if a valid wake-up event is detected.

[3] Vuvd(VCC) > VCC > Vth(det)POR.

[4] Pins ERRN and RXD reflect the state of the wake flag prior to the VCC undervoltage event.

[5] The internal signals at pins STBN, BGE and TXD are set LOW; the internal signals at pins TXEN, SCLK and SCSN are set HIGH.

[6] Except when VCC = 0; in this case BP and BM are floating.

6.1.1 Normal mode

In Normal mode, the transceiver transmits and receives data via the bus lines BP and BM.

The transmitter and the normal receiver are enabled, along with the undervoltage

detection function. The timing diagram for Normal mode is illustrated in Figure 3.
