EXAMPLE 1:
The four bits are programmed as "1111," so that the eight bits of the register are as follows (an "X"
indicates a "Don't Care" bit):
Flash/DC, LED2/STPC, TG4/LED2_STPC, 45 mS/350 µS, X, X, X, X

11
1
  
1 X XXX
RESULT:
The mode settings are as follows:
a. Pin 4 (TG4/LED2_STPC) is configured as a trigger pin (TG4), and the LED2/STPC option will
be ignored.
b. The LED is set as a flash type, with a flash frequency of 3 Hz.
c. The debounce time of the trigger inputs is set to 45 mS.
EXAMPLE 2:
The four bits are programmed as "0000," so that the eight bits of the register are as follows (an "X"
indicates a "Don't Care" bit):
Flash/DC, LED2/STPC, TG4/LED2_STPC, 45 mS/350 µS, X, X, X, X

00
0
  
0 X XXX
RESULT:
The mode settings are as follows:
a. Pin 4 (TG4/LED2_STPC) is configured as either the LED2 or STPC output (determined by bit 6,
LED2/STPC; see next item).
b. Pin 4 is configured as the STPC output pin.
c. LED will be lit constantly during operation.
d. The debounce time of the trigger inputs is set as 350 µS.
2. JUMP (JP) Command:
JP value: Instructs device to jump directly to the voice group corresponding to the value indicated.
The voice group value may range from 0 to 127 (direct jump).
JP R0: Instructs device to jump to whatever voice group is indicated by the value currently stored in
register R0, from 0 to 255 (indirect jump).

B. Ttigger Pin Coupling Effect
The trigger pins (TG1TG4) are built-in 500Kpull high resistor.
If the wire of the input trigger is very close to the speaker wire in the application environment, the
coupling effect will occur. The input voltage of the trigger pin will be unstable, causing the trigger
operation to become abnormal.
An external pull high resistor (Ri) connecting the trigger pin and VDD can resolve this problem. The
value of the Ri depends on your application environment.
