    Register Mapping Register Mapping discusses the registers of the CY8CMBR3102, CY8CMBR3106S, CY8CMBR3108, CY8CMBR3110, ® CY8CMBR3116 CapSense Express™ Controllers. It lists all the registers in mapping tables, in address order. Maneuvering Around the Registers For ease-of-use, this chapter is formatted so that there is one register per page, although some registers use two pages. On each page, from top to bottom, there are four sections: 1.
