Table 4. AUXR1: Auxiliary Register 1
Reset Value = XXXX XXX0
Not bit addressable
Application
Software can take advantage of the additional data pointers to both increase speed and reduce code size, for
example, block operations (copy, compare, search ...) are well served by using one data pointer as a ’source’
pointer and the other one as a "destination" pointer.
