8.4.6.2 Driver and Receiver Function

The TXD_INT and RXD_INT are internal signal paths that behave like the TXD and RXD pins for a physical layer transceiver. During normal operation they are not accessible to external pins. The TCAN4550-Q1 provides a test mode that maps these signals to external pins see Section 8.4.4. The digital logic input and output levels for these devices are CMOS levels with respect to VIO for compatibility with protocol controllers having 3.3 V to 5 V logic or I/O. Table 8-3 and Table 8-4 provides the states of the CAN driver and CAN receiver in each mode.
