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 14.
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 (SPI: SCK)
This signal is the clock line for the synchronous serial interface. That signal is equally valid for
data input and data output.
3.2.7
-Reset In
•
A reset generator (Max 809) is on board; with it in the normal case the reset input is not requi-
red. In this case the reset input has to be connected with VCC, in order to avoid interferences
(see chapter 3.6).
•
If the customer‘s application has to initiate a reset of the UNIGATE
®
IC, then the reset input can
also be connected with a reset output of the customer’s application instead of connecting it with
VCC. Here all specifications of the reset signal, mentioned in chapter 3.2 have to be kept. The
reset-impulse is supposed to last at least 10 ms.
3.2.8
LED LINKACT
A green LED can be connected to this line (see chapter 3.6). This is directly accessed by the
PROFINET processor and is glowing when the Gateway on Port 1 is an operational network (it
will receive link pulses) and flickers if there is network traffic.
