Note : For SLIMbus mode, MODE0 and MODE1 pins are tied to GND directly.
Contact product management if I2C/I2S support is planned. Note : Digital inputs should be grounded, while all other pin
types (analog inputs, outputs and digital outputs)
can be left floating. Note bidirectional digital pins
such as I2S_WS or I2S_CLK default to inputs after
reset and should be grounded.
Note : RF_PA_ON connection to MSM GPIO TX_GTR_THRES pin
J
Connect RF_PA_ON to GND if not planning on enabling.

Note : The line output groud reference sense, LINE_OUT_REF is only for LINE_OUT1
and LINE_OUT2 and only required for single-ended connections made off board.
Route LINE_OUT_REF as a separate trace all the way to the off board connector's
ground pin. Connect LINE_OUT_REF to the CCOMP ground when the line outputs
C6115
are used as differential pair or kept on baard.

(DGMS Guide) MC-C04773-8 : For ESD Protection / Tuning points
When
should apply capacitor under 50pF value for ESD protection with d-class amp
Note 1. If Speaker is located in Main antenna nearby, C6700, C6701 Shunt Cap. should be far from Main antenna.
In case of Speaker phone mode, it could affect a desense of TIS just like GSM850/GSM900/W900 band.
