 Such 16-bit reads and writes are almost twice as cycle-efficient as reading or writing in 8-bit increments, as the extra byte takes only a single extra CPU cycle.
 
-The SDK will provide a C function pair `vera_memcpy_read()` and `vera_memcpu_write()` handle bulk data transfers; it will use this mode of reading and writing without futher intervention by the programmer.
