4. Programmable Power-on Initialization
Whenever the W528xxx
PowerSpeech
is powered on, the programs contained in the 32nd voice
group will be executed immediately. Thus the user can write programs into this group to set the initial
power-on state. If the user does not wish to execute any programs at power-on, an "END" instruction
should be entered in group 32.

PowerSpeech
Program Format
The W528xxx
PowerSpeech
enables users to define the functions of their products using the
W528xxx
PowerSpeech
programming language. An example (for reference only) of the W528xxx
PowerSpeech
program format is shown below. (Explanatory notes follow the example.)
