CE209976 - SPI Slave Select Inversion with Smart IO®
This example demonstrates how to use the Smart IO® Component in PSoC® 4 to invert the output of the serial communication block (SCB) SPI slave select signal. This method can be used for any of the SCB unidirectional signals to invert the signal polarity.
One application of the Smart IO Component is to invert the polarity of SCB communication signals without using an external inverter. This example demonstrates how to invert the SPI Master (SCB) Components slave select signal using the Smart IO Component. The example can be applied to other unidirectional SCB signals (I2C is not supported).
