4.8 DCAN2 and I2C3 Selection (Mux L)
Figure 21 is part of the SoC pinmux table for DCAN2. The SoC device supports additional functions not
shown in the table. The functions shown are intended to reflect those supported on the EVM. These
include:
• Digital CAN Bus (DCAN2): TX, RX
• I2C Serial Bus (I2C3): SCL, SDA
Mux L: Selects between the DCAN2 header and expansion interface, as shown in
selection is made using the IO expander #2 and bits P3, defaulting to on-board DCAN header.
