W528SXX Datasheet, PDF (10/15 Pages) Winbond – ADPCM VOICE SYNTHESIZER(PowerSpeech)

W528SXX
GR = N defines the number of global repeats (from 1 to 16);
m1 and m2 define the number of local repeats (from 1 to 7);
SOUND1 and SOUND2 are the *.WAM files of ADPCM converted voice data;
_FL is the section control setting, for which the parameters F and L are as follows:
F: Voice output frequency setting:
0 = 4 KHz, 1 = 4.8 KHz, 2 = 6 KHz, 3 = 8 KHz;
L: LED output setting:
1: ON
0: OFF; and
[1FFFF] is a period of silence of length 1FFFF;
H4, T4: Represent head and tail ADPCM files, respectively.
E. Programmable Power-on Initialization
Whenever the W528xxx is powered on, the program contained in the 32nd voice group will be
executed after the power-on delay (about 160 mS), so the user can write a program into this group to
set the power-on initial state. If the user does not wish to execute a program at power-on, an "END"
instruction should be entered in group 32. The W528xxx power-on initialization process can be
interrupted by trigger inputs.
F. Progamming Examples
This section presents several examples of how the functions of the W528xxx may be programmed.
Customer programs should be written in ASCII code using a text editor; after compiling, the sound
effects resulting from the programs can be tested using a Winbond demo board.
EXAMPLE1: Four playing mode settings:
a. One-Shot Trigger Mode
0: LD EN, 0x01
; Enable TG1 falling edge input only.
H4 + sound1 + T4
