3.2.1
-Boot enable
The IC is started in the firmware update mode with the level GND during the power up process.
See also chapter 13 on page 36.
3.2.2
Load out (SPI-Master: SS0-)
Strobe signal for the synchronous serial interface. With the positive edge at this output data is
taken from the connected shift registers to the physical outputs.
In SPI mode this Pin serves as a low-active Slave-Select-Signal.
3.2.3
Data out (SPI-Master: SS1-)
On this line data is output on the synchronous serial interface. The most significant bit of the data
is output first.
In SPI mode this Pin serves as a low-active Slave-Select-Signal.
3.2.4
Data In (SPI: MISO)
Data is read in on the synchronous serial interface via this signal. The most significant bit of the
data is expected first.
In SPI mode this Pin serves as data transfer from Slave to Master.
3.2.5
Load In (SPI: MOSI)
This pin is the strobe signal for the input data of the synchronous serial interface.
In SPI mode this Pin serves as data transfer Master to Slave.
3.2.6
Clock
This signal is the clock line for the synchronous serial interface. That signal is equally valid for
data input and data output.
