9-6 FADR Command

The FADR command transfers data stored in the TMP register to the phrase address register of

the corresponding channel at the rise of the WR pulse.

For the phrase address, the user specification phrases have been set by an analysis tool, and the

playback system, sampling frequency and start and stop address of voice data have been

registered to the address management area.

When the phrase address is set and the START command is input, the LSI reads data of the

address management area, and starts voice synthesis.

Since the phrase address is set by D7-D0, a maximum of 256 phrases can be set. The edit function

can be used for phrase addresses, so not only one phrase but combinations with other phrases

are possible.

9-7 DADR Command

The DADR command transfers data stored in the TMP (1-7) register to the start and stop address

register of the corresponding channel at the rise of the WR pulse.

For the direct address, the playback system, sampling frequency, and start and stop address of

voice data is directly input from the microcomputer without using the address management

area.

Direct address playback system is available with channel 1 to 4, and not available with channel

5 to 8.

Since the phrases that can be set at a phrase address is a maximum of 256, if voice data exceeds

256 phrases, use this command. Data on the playback system, sampling frequency, and start and

stop address of voice data is displayed when an analysis tool is used.

Data on the playback system, sampling frequency, and start and stop address of voice data is

input to the TMP1 to TMP7 registers divided in 7 steps, unlike the data input of other commands.

Figure 9-4 shows the input method.
