W529XX Application Note
- 26 -
(4) Macro:
If the program possesses many repetitive sections, a "Macro" may be used to provide a more
efficient structure. In a macro program, the "label:" is illegal because it isn't a subroutine. After compilation the
macro will be extended and inserted into the main program. So although a macro can offer more convenience in
program editing it cannot reduce ROM size. It is also possible to call a macro within another macro program.
Eight levels of depth can be used in programming. Note that all of the unknown parameters must be transferred
from the main program. The "ENDM" command will end the macro program.
Illegal writing:
macro chk_keyin label0, label1, label2
mv acc,r6
jp label0 @r6=0
mv acc,r6
sub acc,1
label0:
.
endm
macro name: chk_keyin
transmitted paramaters: label0, label1, label2
(5) Macro begin line:
This includes the keyword "Macro" to declare "macro start", a user given name for the
macro and the transmitted parameters. The format is as follows:
first item
second item
next
Macro
Name
parameters
The individual transmitted parameters have a " , " between them.
(6) Macro end line:
"endm" must be added at the end of the macro.
(7) Declarations:
The output frequency and LED on/off state.
LED on/off:
--LED0: LED off (default)
--LED1: LED on
Output frequency:
--FREQ0: 4.8 KHz
--FREQ1: 6 KHz (default)
--FREQ2: 8 KHz
--FREQ3: 12 KHz
(8) program body:
Write application program and speech operations, including the following:
Define entry point of speech group.
Determine number of global repeats.
Describe speech equations.
