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

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

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).
