Register Reference
The section discusses the registers of the enCoRe V device. It lists all the registers in mapping tables, in address order.
Register Conventions
The register conventions specific to this section are listed in the
following table.  
Register Mapping Tables
The enCoRe V 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: Bank 0 (user space) and Bank 1 (configu-
ration space). The XIO bit in the Flag register (CPU_F) deter-
mines which bank the user is currently in. When the XIO bit is
set, the user is said to be in the “extended” address space or the
“configuration” registers.
