Register Mapping Tables

The PSoC device has a total register address space of 512 bytes. The register space is also referred to as IO space and is broken into two parts. The XOI bit in the Flag register determines which bank the user is currently in. When the XOI bit is set, the user is said to be in the “extended” address space or the “config- uration” registers.

Note In the following register mapping tables, blank fields are Reserved and must not be accessed.
