3.8 Safety option with SAK-CIC61508 (optional if not with TC1387)
The safety device is only assembled if the board is with TC1387 or with the safety option.
The SAK-CIC61508 is connected to the SSC0 of the microcontroller and use the line
SLSO01 (P3.6) as chip select.
There are 4 LED’s for indication the state of the safety device (SYSDISA, SYSDISB,
SYSDISC, VDDP_CIC).
On this board exists 4 potentiometer to stimulare the sense inputs of the safety device.
Sensor inputs A and B can be connect to a potentiometer (JP201, JP202 , pos. 2-3) or
to the core voltage of the microcontroller (JP201, pos. 1-2) for input A or to the port
voltage of the microcontroller (JP202, pos. 1-2) for input B.
With switch S202 it is possible to reset the safety device. If JP203 is set, then with S202
is also reset the microcontroller and the safety device is reset by a power on reset of the
microcontroller.
The safety device can be reprogrammed via JTAG and X203.
3.9 Other peripherals
For all other peripherals there are no special plugs on the board. The peripheral signals
are available on the different connectors. See
“Connector Pin Assignment” on
Page 7-1 .
Note: - SLSO00 is used as chip select for the serial eeprom on board.
3.10 Toggle LED’s
Port 5 pin 0 up to pin 7 are connected to single LED’s (D501... D508) and can be
controlled by Software. This status LED’s are low active.
3.11 Debug System
3.11.1 OCDS1
The OCDS1 signals are connected to the IDC16 plug (X401). They work with the port
supply of +3.3V. For pinout of the connector see
Figure 7-7 . You can connect any
debugger to this connector.
The signals /BRKIN and /BRKOUT are not connected per default. If you need this signals
in the connector then assemble R425 and R424 with a 0R resistor.
If you connect a debug hardware make sure that the MiniWiggler (see
“MiniWiggler”
on Page 3-2 ) is not activ (ACTIV LED is off) and on the DAP connector (X402) is no
hardware connected or the hardware is tristated.
