DCAN2/I2C3 Selection (Mux L)

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 DCAN2 to CAN/CAN-FD phy and I2C3 for display panel control. The selection is
made using the IO expander #2, bits P3, defaulting to I2C3. Additional control is provided by IO expander
#2 bit P5, when enables the DCAN2/I2C3 signals access to the expansion interface (default is no access).
