If MODE1 register bit AI1 = 0 and AI0 = 1 and if the Control register = 1000 0101, then the
register addressing sequence will be (in hexadecimal):
05  06  …  19  0A  0B  …  19  0A  0B  … as long as the master
keeps sending or reading data.
Remark: Writing to registers marked ‘not used’ will return NACK.
