JUMPER POSITION JUMPER DESCRIPTION
JMP1 2-3 When connecting 2-3, mic bias comes from the MICBIAS pin on the device; when
connecting 1-2, mic bias is supplied from the power supply through a resistor, which
the user must install.
JMP2 Installed Connects on-board Mic to Left Microphone Input.
JMP3 Installed Connects on-board Mic to Right Microphone Input.
JMP4 Installed Provides a means of measuring IOVDD current.
JMP5 Installed Provides a means of measuring AVDD_ADC current.
JMP6 Installed Provides a means of measuring DVDD current.
JMP7 Installed Provides a means of measuring DRVDD current.
JMP8 Installed Provides a means of measuring AVDD_DAC current.
JMP9 Installed Connects Analog and Digital Grounds.
JMP10 3-5 When connecting 3 to 5, I
2
C is selected as control mode; when connecting 1 to 3, SPI
is selected as control mode. When connecting 3 to 4, mode selection can be made by
a logic level at J16.12
JMP11 3-5 In I
2
C control mode, this jumper sets the state of A0. When connecting 3 to 5, A0 = 0;
when connecting 1 to 3, A0 = 1. In SPI control mode, connecting 3 to 4, SPI /SS is
provided from J16.2
JMP12 3-5 In I
2
C control mode, this jumper sets the state of A1. When connecting 3 to 5, A1 = 0;
when connecting 1 to 3, A1 = 1. In SPI control mode, connecting 3 to 4, SPI SCLK is
provided from J16.3
JMP13 Installed When installed, shorts across the output capacitor on HPLOUT; remove this jumper if
using AC-coupled output drive
JMP14 Installed When installed, shorts across the output capacitor on HPLCOM; remove this jumper if
using AC-coupled output drive
JMP15 Installed When installed, shorts across the output capacitor on HPROUT; remove this jumper if
using AC-coupled output drive
JMP16 Installed When installed, shorts HPLCOM and HPRCOM. Use only if these signals are set to
constant VCM.
JMP17 Installed When installed, shorts across the output capacitor on HPRCOM; remove this jumper if
using AC-coupled output drive
JMP18 Open Selects on-board EEPROM as Firmware Source.
JMP19 Open When installed, allows the USB-MODEVM to hardware reset the device under user
control
The following section provides information on using the TLV320AIC33EVM-PDK, including set up,
program installation, and program usage.
A block diagram of the TLV320AIC33EVM-PDK is shown in Figure 1 . The evaluation kit consists of two
circuit boards connected together. The motherboard is designated as the USB-MODEVM Interface board,
while the daughtercard is the TLV320AIC33EVM described previously in this manual.
