Hello,

I see in SPRUHX5G figure 17-6 SPI Modle Slave Configuration a problem:

I think, the direction of this AND is not correct.

In SPI slave mode, the SPICLK signal is an input to the MCU. Furthermore the SPISTE signal gates the SPICLK signal. When SPISTE = 0, the SPICLK is allowed to pass to the SPI. When SPISTE = 1, the SPICLK signal is blocked from the SPI.
