Multiple Write and Multiple Read operations enable the host processor to access sequential blocks of
the data in the WM8321 register map faster than is possible with single register operations. The auto-
increment option is enabled when the AUTOINC register bit is set. This bit is defined in Table 12.
Auto-increment is enabled by default.
