W83791SD/SG is a programmable speech synthesizer with 9-bit current DAC output that can connect to speaker or LINE_OUT by the AC'97 audio codec. It supports 1 CPU present or absent event trap, 5 external event traps, and 127 internal programmable event traps to trigger maximum 133 different speech output. If more than two events happen simultaneously, the priority set is: SLOTOCC# > EVNTRP1 > EVNTRP2 > EVNTRP3 > EVNTRP4 > EVNTRP5 > 127
Programmable events (Bank0 index 09h).
For the application of error messages from BIOS, 127 Programmable events are enabled with a watch dog timer. The time interval is programmable and events will be triggered when time out.
External flash memory interface with Winbond W55FXX is flexible to change warning voice message and support on-line programming flash data through I2CTM interface. An external resistor is added to provide ring oscillator.
Through the application software or BIOS, the users can edit and change the voice database in the serial flash chip by themselves under O.S. A free Windows AP --- Voice EditorTM is provided for the voice editing, which can accept the *.wav file as the voice database resource. Users can replace the voice with which they like through the S/W.
W83791SD/SG also provides two addresses setting pins A0 & A1 for different I2CTM address and can be connected up to 4 devices if necessary.
