JAJSH69B January 2018 – November 2019 TCAN4550-Q1
This is the normal operating mode of the device. The CAN driver and receiver are fully operational and CAN communication is bi-directional. The driver translate a digital input on the internal TXD_INT signal from the CAN FD controller to a differential output on CANH and CANL. The receiver translates the differential signal from CANH and CANL to a digital output on the internal RXD_INT signal to the CAN FD controller. Normal mode is enabled or disabled via the SPI interface.
If an under voltage event has taken place and cleared, the interrupt flags have to be cleared before the device can enter normal mode.
