TITLE:
Delay for some period by playing melody or sound effect
REVISED DATE : 13, JUNE, 1998
REVISED VERSION : 1.0
APPLY TO CHIPS : EM57000 Series Chip
APPLY TO SOFTWARE : ALL EM57000 series coding system above version 2.1
SEE ALSO:
1. In program user may need to implement delay function. For example
it may be necessary to delay ( idle ) for 30 sec waiting user
input, if there are no input comes after 30 sec, chip will power
down automatically.
2. In most condition user may implement delay function with internal
timer. But he can also implement this function with speech or
melody.
3. When use internal timer, please note that for EM57000 series,
internal timer is adjusted.
Following is the simple example for delay with internal timer :
SAVEPWR:
PLAY TAIL.WAV #8 ; Force D/A current to low
CJP SAVEPWR
; Now Delay for 10 sec.
MOV TIMER, #1 ; Set timer for 8 ms interval
MOV M1 #0 ; Initial condition
MOV M2 #0 ; Initial condition
MOV M3 #0 ;
RSTC
LVL1:
CJC UPDATE
JMP LVL1
UPDATE:
CALL KEYSCAN ; Keyboard scan routine ( every 8 ms )
CALL OUTPUT ; Output routine ( every 8 ms )
MOV A M1
INCA
MOV M1 A
CAJE #0 UPDATE1 ; 8 * 16 = 128 ms passed
JMP LVL1
