2.5 Push Buttons and Switches

This section covers the various button and switch locations on the EVM.

SW1 connects the USB2ANY driver SPI signals to the SDO / SDI / SCLK / CS on the EVM. The "ON" position for this switch is when the switch is in the right-most position.

When a Total Phase product or external SPI driver is connected, disable the 4 SPI signals on SW1.

Push button S2 puts the USB2ANY circuit into programming mode when depressed while the TXE81XXEVM is being plugged in. This is an alternative method to programming the USB2ANY circuit. The easier method is to short J18 instead. If not programming the USB2ANY circuit, there is no further use case for S2.

S1 is a side button used for manually resetting the TXE81XX. When S1 is pressed, it shorts RESET of the TXE81XX to GND. A pull-up resistor is used to bring the voltage on RESET back up to VCC.
