7.3.3.3 Transition from SIC Mode to FAST TX Mode

When the TXD pin is LOW for at least tSELECT, FAST TX mode becomes pre-selected. After this pre-selection, two valid consecutive low-to-high rising edges on TXD within tSymbolNom will cause the device to transition to FAST TX mode as shown in Figure 7-8 below. The CAN transmitter will switch from dominant to level_0 within tProp(BusDom-BusLevel0) after the second valid consecutive low-to-high rising edge on TXD.

TCAN6062-Q1 TCAN6062V-Q1 FAST TX Mode SelectionFigure 7-8 FAST TX Mode Selection
In FAST TX mode, both the FAST receiver and FAST transmitter are active. The FAST receiver decodes the information on the CAN bus using FAST RX thresholds and passes this information to RXD. The FAST transmitter decodes the PWM on the TXD pin and drives the corresponding level_0 or level_1 signal onto the CAN bus. See Table 7-5 and Section 7.3.3.4.3.
