General Description

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.
