This register sets the base address of the memory mapped audio interface control register block. This is a 128-byte block of registers
used to control the audio FIFO and codec interface, as well as to support VSA SMIs. Bits [11:0] are read only (0000 0000 0000), indicat-
ing a 4 KB memory address range. Refer to Table 6-38 on page 262 for the audio configuration register bit formats and reset values.
