b. When the falling edge of TG1 goes active, the EN register will cause TG1 to interrupt the
current playing state and jump immediately to voice group 0, the voice group that corresponds
to 1F.
c. No action will be taken when the other trigger pins are pressed, because the corresponding bits
are set to "0."
LD STOP, operand:
This instruction loads the operand message into the STOP register to set the output levels of the stop
signals. The initial value of the STOP register is "XXXXX111."
a. This register is used to program the output levels of the three STOP signals, STPA, STPB,
and STPC. Only three of the bits in the register are used, as shown below (an "X" indicates
"Don't care"):
Bit:
7
6
5
4
3
2
1
0
Stop:
X
X
X
X
X
STPC
STPB
STPA
b. When a particular STOP bit is set to "1," The corresponding stop signal will be a high output;
when a bit is set to "0," the corresponding stop signal will be a low output.
EXAMPLE:
The instruction "LD STOP, 0x43" is programmed.
EXPLANATION:
a. "43" is a hexadecimal value equal to a binary value of "0100 0011."
b. These 8 bits of data represent the following settings:
X,
0
X,
1
X,
0
X,
0
X,
0
STPC,
0
STPB,
1
STPA
1
RESULT:
a. The STPA and STPB outputs will be high outputs.
b. The STPC signal will be a low output.
c. The sixth bit "1" is a "Don't Care" bit and so has no effect on the stop signal output
settings.
LD MODE, operand:
This instruction is used to select various operating modes. It loads an operand message into the
MODE register to select one mode from each of four pairs of modes, which correspond to bits 4
through 7 of the register (bits 0 to 3 are "Don't Care" bits). The four pairs of modes and the
corresponding bits are as follows:
Bit:
7
6
5
4
3
2
1
0
MODE:
Flash/DC
LED2/STPC
TG4/LED2_STPC
45 mS/350
μ
S
X

X
A "1" for one of these bits selects the first of the pair of modes indicated; a "0" selects the second of
the pair. The initial value of the mode register is "1111XXXX."
