ed Audio Status/Control Register (Index 2Ah) is ‘set’. If the VRA bit is ‘clear’, all writes are ig-
nored and the register reads back BB80h; corresponding to a 48 kHz sample rate. If the VRA
bit is ‘set’, seven standard sample rates are available. If a sample rate written to the register is
not directly supported, the attempted value to be written will be decoded according to the ranges
indicated in Table 7. All register read transactions will reflect the actual value stored (column 2
in Table 7) and not the one attempted to be written.
Extended Audio Status/Control Register (Index 2Ah) is ‘set’. If the VRA bit is ‘clear’, all writes
are ignored and the register reads back BB80h; corresponding to a 48 kHz sample rate. If the
VRA bit is ‘set’, seven standard sample rates are available. If a sample rate written to the reg-
ister is not directly supported, the attempted value to be written will be decoded according to
the ranges indicated in Table 7. All register read transactions will reflect the actual value stored
(column 2 in Table 7) and not the one attempted to be written.
Front DAC Sample Rate. The SR[15:0] bits can only be written when the VRA bit of the Extend-
BB80h. This value corresponds to 48 kHz sample rate..
Left/Right ADC Sample Rate. The SR[15:0] bits can only be written when the VRA bit of the
BB80h. This value corresponds to 48 kHz sample rate.
