This document contains information on a new product. Specifications and information herein are subject to change without notice.

3.5.4 JP3 - FST_1 Connection

This set of jumpers determines which frame sync clock source is used for the AKM DAC4_6. The F position

directs the ESAI_0 FST signal to DAC4_6. Position G directs the ESAI_1 FST signal to DAC4_6, and

population of both jumpers will synchronize/short the two ESAI port FST lines.

Note: Position F should always be populated when using a 56362 or 56364 daughterboard.

3.5.5 JP4 – SCKT_1 Connection

This set of jumpers determines which serial clock source is used for the AKM DAC4_6. Position H directs

the ESAI_0 SCKT signal to DAC4_6, position I directs the ESAI_1 SCKT signal to DAC4_6 and population

of both jumpers will synchronize/short the two ESAI port SCKT lines.

Note: Position H should always be populated when using a 56362 or 56364 daughterboard.

3.5.6 JP5 - FSR_1 Connection

This jumper connects/shorts the FSR and FSR_1 signals together. No jumper means that the FSR_1 signal

stops at the header.

3.5.7 JP6 - SCKR_1 Connection

This jumper connects/shorts the SCKR and SCKR_1 signals together. No jumper means that the SCKR_1

signal stops at the header.

3.5.8 JP7 - DSP MUTE Control

This jumper controls the mute signal when used in conjunction with the Software Architecture or GPIO

control. With the jumper in place, the mute control is connected to the DSP GPIO pin PB12. No jumper

means that mute functionality will only be controlled by the motherboard.

3.5.9 JP8 - INT_0/SPDIF Error Flag Connection

This jumper connects the error flag signal from the AKM 4114 to the DSP GPIO pin PB15. This allows the

DSP to be informed of the status of the AKM 4114 S/PDIF receiver. If the connection is not desired this

jumper can be removed.

3.5.10 JP9 - SDO5/SDI0 Configuration

This jumper set controls the signal connections of SDO5/SDI0. Depending on the ESAI setting in the DSP,

this pin can be configured as an input or an output. A jumper in position N feeds the SDI0 signal from the

ADC2 microphone source. A jumper in the O position feeds the SDO5 signal to DAC4_6.

3.5.11 JP10 SDO4/SDI1 Configuration

This jumper set controls the input source for SDI1. A jumper in the P position feeds the SDI1 signal from the

AKM 4114 S/PDIF receiver. A jumper in the Q position feeds the SDI1 signal from ADC1. There is no

available jumper setting for use of the SDO4 signal.
