E1. The SPI0_DOUT and SPI1_OUT signals do not disable their drive and become Hi-Z
when the associated chip select pin is high. This applies to all pin MUX locations for the
SPI_DOUT signals. If there are multiple write only devices on the same SPI bus, then this
is not an issue. This only becomes an issue when there are other read/write devices on the
same SPI bus. The workaround is to add an external buffer chip, such as 74LVC1G125
between the SPI_DOUT pin and the SPI bus, with the enable connected to the chip select
signal.
