The sound feature values are stored in independent
registers. The first selection of the registers is achieved by
the choice of data type that is transferred (‘STATUS’ or
‘DATA’ transfer). This is performed in the address mode
using bit 1 and bit 0, see Table 4,. The settings that can be
controlled with ‘STATUS’ transfer are given in table 5, and

the settings that can be controlled using ‘DATA’ transfer
are given in table 6.
The second selection is performed by the 2 MSBs of the
data byte (bit 7 and bit 6). The other bits in the data byte
(bit 5 to bit 0) is the value that is placed in the selected
registers.
