3. Specification
3.1. EROFF jumper pin
EROFF jumper pin is jumper pin that switch the connection of EROFF pin of Speech Synthesis LSIs.
EROFF
Contents
NML
EROFF pin is connected to CN1,CN2.
PRG
EROFF pin is connected to IOVDD.
Set to NML when connecting to SDCB3 for use. EROFF pin is controlled from SDCB3.
When this board is used by itself, setting PRG enables the serial flash memory interface of Speech Synthesis LSIs.
3.2. OE jumper pin
OE jumper pin is a jumper pin that enables or disables the signal input/output of CN1 pins to the serial flash memory pins.
OE
Contents
NML
Enable: The pins of the serial flash memory are input/output from the pins of CN1.
PRG
Disable: The pins of the serial flash memory do not input/output from the pins of CN1.
Set to NML when connecting to SDCB3 for use.
When this board is used by itself, the serial flash memory interface signal of Speech Synthesis LSIs and CN2 signal are
input/output to the serial flash memory when OE jumper pin is set to PRG.
3.3. IOVDD jumper pin
IOVDD jumper pin is jumper pin that switch the connection of IOVDD pin of Speech Synthesis LSIs.
IOVDD
Contents
SDCB3
IOVDD pin is connected to the output (3.0V) of the LDO mounted on this board.
CN2
IOVDD pin is connected to 23pin of CN2.
Set to SDCB3 when connecting to SDCB3 for use.
When this board is used by itself, power can be supplied to IOVDD terminal of the speech synthesis LSI from 23pin of
CN2 when IOVDD jumper pin is set to CN2.
3.4. OUT jumper pin
OUT jumper pin is jumper pin that switch the connection of SPP pin of Speech Synthesis LSIs.
OUT
Contents
LOUT
SPP pin is connected to LOUT jack.
SP
SPP pin is connected to SP jack.
3.5. LOUT jack
LOUT jack is a jack where the signal from LOUT pins of Speech Synthesis LSIs is output via the speaker amplifier.
Set Mode of Play setting of SDCB Controller to Line AMP(SPP). (Refer to Speech LSI Utility User's Manual.)
Connect a monaural speaker.
