PSoC 4 1.2 Volt Comparator (CSD Comp)
The 1.2 Volt Comparator (CSD_Comp) component provides a hardware solution to compare one input voltage with the internal 1.2 V reference (Vref) of the PSoC™ 4000 family of devices. The CSD_Comp component makes use of the comparator that is present in the Capacitive Sensing Delta-Sigma Modulator (CAPSENSE™ CSD) block. This comparator functionality is only present on the PSoC™ 4000 family of devices and only available when not using the CAPSENSE™ CSD block for Capacitive Sensing. You can sample the output in software or route it to a GPIO. There are two speed levels to allow you to optimize for response time or power consumption.
