Table 5. ZNEO CPU Control Registers
Many ZNEO CPU products support external data and address buses for connecting to
additional external memories and/or memory-mapped peripherals. The external addresses
are used for storing program code, data, constants, and stack, etc. Attempts to read from or
write to unavailable external addresses is undefined.
The ZNEO CPU accesses data in big endian order, that is, the address of a multi-byte word
or quad points to the most significant byte.
