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 deter-
mines 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 “configuration” registers.
Note In the following register mapping tables, blank fields are
