All on-chip peripheral registers are accessed in the I/O address space. All I/O operations
employ 16-bit addresses. The upper byte of the 24-bit address bus is undefined during all
I/O operations (ADDR[23:16] =

Registers at unused addresses within the
erals are not implemented. Read access to such addresses returns unpredictable values and
Write access produces no effect.
