ww1.microchip.comVIO exceed their undervoltage levels. Once powered on, CANH and CANL will enter a high-impedance state if the voltage level at V DD drops below the undervoltage level, providing voltage brown-out protection during normal operation. In Normal mode, the receiver output is forced to Recessive state during an undervoltage condition on VDD. In ...
