8.8 Display Test Register
With the display test register 0Fh all LED can be tested. In the test mode all LEDs are switched on at maximum brightness (duty cycle 31/32). All
programming of digit and control registers are maintained. The format of the register is given in Table 13 .

Note: The AS1100 remains in display-test mode until the display-test register is reconfigured for normal operation.
8.9 No-Op Register (Cascading of AS1100)
The no-operation register 00h is used when AS1100s are cascaded in order to support more than 8 digit displays. The cascading must be done
in a way that all DOUT are connected to DINof the following AS1100. The LOAD and CLK signals are connected to all devices. For a write
operation for example to the fifth device the command must be followed by four no-operation commands. When the LOAD signal finally goes to
high all shift registers are latched. The first four devices have got no-operation commands and only the fifth device sees the intended command
and updates its register.
8.10 Reset and External Clock Register
This register is addressed via the serial interface. It allows to switch the device to external clock mode (If D0=1 the CLK pin of the serial interface
operates as system clock input.) and to apply an external reset (D1). This brings all registers (except reg. E) to default state. For standard
operation the register contents should be "00h".
