TLV320AIC34 data sheet errors

TLV320AIC34 data sheet lacks of a diagram block according with functional description. It is not clear which signals can use bypass paths described in

ANALOG INPUT BYPASS PATH FUNCTIONALITY paragraph (page 42 SLAS538A).

There is a mismatch, because LINE1LP_x and LINE1LM_x signals are given in ANALOG INPUT BYPASS PATH FUNCTIONALITY but Simplified Block Diagram on page 3 shows LINE2LP_x and LINE2LM_x connected to output drivers.

Again, in ANALOG FULLY DIFFERENTIAL LINE OUTPUT DRIVERS paragraph (page 45) LINE1LP_x and LINE1LM_x signals refer to the signals that travel through the analog input bypass path to the output stage, but Figures 33 and 34 show LINE2LP_x and LINE2LM_x.

There isn't a diagram showing analog input bypass mode configuration.

About PASSIVE ANALOG BYPASS DURING POWER DOWN (page 43) fig 32 is in addition to simplified diagram (page 3).

It seems by register 40 page 68 LINE2LP_x and LINE2LM_x, LINE2RP_x and LINE2RM_x are the correct signals for analog input bypass path. Is it correct ?
