+<dd><p>A register is a memory location on the ASSP hardware to store
+data that relates to the operation of that hardware. The Symbian platform
+support registers that can store 8, 16, 32 and 64–bit data.</p></dd>

+<dd><p>ASSP is an integrated circuit consisting of CPU, Memory Management
+Unit (MMU), cache and a number of on-chip peripherals, which is intended
+to be used in a class of devices. Typical examples include UARTs,
+timers, LCD controller that are designed and marketed by a silicon
+vendor.</p></dd>
