Open/Short Test Register (0x09)
The AS1119 can detect open and shorted LEDs. To start this test the according bits have to be set. The result of the open/short test is written in
the Open/Short staturs register (see Table 26) . The default setting of this register is 0x00.

The Open/Short test is only checking LEDs which are defined as ON in the Data Frame Registers Table 8 on page 14 or Table 12 on
page 18 . With the bit1 (Full Matrix) all LEDs of the matrixes will be defined as ON and will be tested intependently from the content of the Data
Frame Register. The function of bit1 is only available during the open/short test and not during normal operation.
Shutdown Register (0x0A)
The default setting of this register is 0x00. To get the AS1119 operational the bit D0 has to be set to ‘1’.

I2C Interface Monitoring Register (0x0B)
This register is used to monitor the activity on the I2C bus. If a deadlock situation occurs (e.g. the bus SDA pin is pulled to low and no communi-
cation is possible) the chip will reset the I2C interface and the master is able to start the communication again.
The time window for the reset of the interface of the AS1119 can bes set via 7 bits from 256μs to 33ms. The default setting of this register is
0xFF.
