Reception The analog CAN bus signals are converted into a digital signal at RxD via the differential input receiver. In normal mode and RxD only, the split pin is used to stabilize the recessive common mode signal. Permanent Recessive Clamping ...
Page 11
Standby Mode In the standby mode, transmission and reception of signals is deactivated. This is the first step of reducing the current consumption. The internal voltage regulator control pin (INH) is still active, so all external (INH controlled) powered devices ...
