Pin Configuration
3.3
Hints for Unused Pins
It must be ensured that the correct configurations are also selected, i.e. in case functions are not used that
they are disabled via SPI:
•
WK1/2/3: connect to GND and disable WK inputs via SPI
•
HSx: leave open
•
LINx, RXDLINx, TXDLINx, CANH/L, RXDCAN, TXDCAN: leave all pins open
•
RO / FOx: leave open
•
INT: leave open
•
TEST: connect to GND during power-up to activate SBC Development Mode;
connect to VS or leave open for normal user mode operation
•
VCC2: leave open and keep disabled
•
VCC3: See
Chapter 8.5
• VCAN: connect to VCC1
•
n.c.: not connected; internally not bonded; connect to GND
•
N.U.
: Not Used; Used for internal testing purposes only. Do not connect, leave open, i.e. not connected to
any potential on the board. In case N.U. pins are connected on the board an open bridge has to be foreseen
to avoid external disturbances. The bridge can be shorted by a 0
Ω
resistance if signal is needed.
3.4
Hints for Alternate Pin Functions
In case of alternate pin functions, selectable via SPI, it must be ensured that the correct configurations are also
selected via SPI, in case it is not done automatically. Please consult the respective chapter. In addition,
following topics shall be considered:
•
WK1..2: The pins can be either used as HV wake / voltage monitoring inputs or for a voltage measurement
function (via bit
WK_MEAS
). In the second case, the WK1..2 pins shall not be used / assigned for any wake
detection nor cyclic sense functionality, i.e. WK1 and WK2 must be disabled in the register
WK_CTRL_2
and
the level information is to be ignored in the register
WK_LVL_STAT
.
•
FO2..3: The pins can also be configured as GPIOs in the
GPIO_CTRL
register. In this case, the pins shall not
be used for any fail output functionality. The default function after Power on Reset (POR) is FOx.
