This device supports several speech synthesis algorithms that permit tradeoffs meet price performance requirements various markets. SC-691 implements unique feature playing single channel music along with speech data concurrently. This feature allows user speak certain phrase with single channel music background. SC-691 optimized support 4-bit wide data transfer protocol. device status bits three control bits that control communication protocol between master slave. SC-691 also (command/data) which differentiates between command speech data feeding into slave. 4-bit mode, various commands sent slave during speech perform various tasks. SC-691 also supports 8-bit wide data transfer support commands disabled during speaking-a-phrase. When speaking-a-phrase 8-bit mode complete, SC-691 switches back 4-bit mode receive next command. Switching between mode mode permitted between speech data files.

Read Operation Master
process read operation master same either 4-bit 8-bit mode. read operation master happens when slave wants send something master. read process initiated slave pulling OUTRDY_ when ready. following events take place during read operation: SC-691 puts data sent master internal bus. SC-691 sets OUTRDY_ indicate that ready send data microcontroller. microcontroller sets R/W_ high indicate read operation. microcontroller sets STROBE_ low. data available external data-bus this point. microcontroller reads data from bus. microcontroller sets STROBE_ high. SC-691 also pulls OUTRDY_ high rising edge STROBE_. data taken from external data-bus after STROBE_ goes high. microcontroller should latch read data while STROBE low. When microcontroller sets STROBE_ high, SC-691 sets OUTRDY_ high indicate that data been successfully transferred. Sequence events single read operation:
