7.3.3.4.3 PWM Decoding in FAST TX Mode

In FAST TX mode, the duty cycle of the TXD input determines the transmitter's output to the CAN bus. When the input PWM to TXD is low for more than 50% of tSymbolNom, corresponding to a PWM duty cycle less than 50%, the FAST transmitter transmits a level_0 output to the CAN bus.

When the input PWM to TXD is high for more than 50% of tSymbolNom, corresponding to a PWM duty cycle greater than 50%, the FAST transmitter transmits a level_1 output to the CAN bus.
