WM8750-EV1M
LINE SUBMIT SETUP
By pressing the ‘Line Setup’ button, the software writes to the device setting the
L/RLINE_IN1 through the analogue path to the L/ROUT1 and L/ROUT2 outputs. As with the
setups previously described, this is to ease the initial use of the WM8750 until the user
becomes familiar with both device and software operation.
