The PSoC Core section discusses the core components of a PSoC device with a base part number of CY8C20x34 and the
registers associated with those components. The core section covers the heart of the PSoC device, which includes the M8C
microcontroller; SROM, interrupt controller, GPIO, and SRAM paging; multiple clock sources such as IMO and ILO; and
sleep and watchdog functionality. This section contains these chapters:
