the low-power differential receiver of the transceiver. For applications running in low-power
mode, this allows the bus lines to be monitored for activity even if there is no supply
voltage on pin V
For versions of the TJA1042 without a V
This sets the signal levels of pins TXD, RXD and STB to levels compatible with 5 V
microcontrollers.
