The CP2532/CP2528 is 12/8 channels capacitive touch panel controller, used for scroll, navigation and selection detection.The controller contains SPI or I2C serial interface, extendable GPIO, high PSRR LDO and in-built OSC.The touch status can be read via serial interface or GPIO.GPIO can be configured to open drain mode.Particularly, adjacent sensor suppression
