Register description: New Map
Mapping of two registers is available on the STA381BWS, the selection is done by setting
register 0x7E bit D7. By default, 0x7E is set to 1 and refers to a map that is not compatible
with previous Sound Terminal devices. This register’s mapping is also called “New Map”.
To keep compatibility with previous Sound Terminal devices, 0x7E bit D7 must be set to 0
after device turn-on and after any reset (via SW or via external pin). Please refer to
Section 7: Register description: Sound Terminal compatibility
device compatibility.
Missing addresses are to be considered as reserved.
