For detailed register information, reference the
PSoC Programmable System-on-Chip Technical Reference
Manual.
Register Conventions
The register conventions specific to this section are listed in the
following table.
Register Mapping Tables
The PSoC device has a total register address space of 512
bytes. The register space is referred to as I/O space and is
divided into two banks. The XOI bit in the Flag register (CPU_F)
determines which bank the user is currently in. When the XOI bit
is set the user is in Bank 1.
Note In the following register mapping tables, blank fields are
reserved and must not be accessed.
