The PSoC Core section discusses the core components of a PSoC device with a base part number of CY8CTMG20x or
CY8CTST200 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 includes these chapters:
