Production Data
HARDWARE CONTROL MODE
w
When the MODE pin is held ‘low’ the WM8741 is set to hardware control mode and a limited feature
set can be configured.
Table 44 MODE/LRSEL Hardware Control Pin Function
DSD AND PCM MODE SWITCHING
The audio interface mode can be switched between DSD Direct and PCM by controlling the state of
pin DSD. It is recommended that the chip is forced into a MUTE state before dynamically switching
modes.
Table 45 SCLK/DSD Hardware Control Pin Function
AUDIO INPUT FORMAT
Under hardware control, it is possible to select between four different modes of operation for the
PCM audio interface.
