Watchdog function coding mask, function code 17...32, WD_FCM_17_32
Read/write
0xFFFF
Same function as above, however, with the function codes 17 to 32.
FC 17 Bit 0
FC 18 Bit 1
...
FC 32 Bit 15
These codes are currently not supported, for this reason the default value should
not be changed. Changes to the register value can only be made if the watchdog
is deactivated. It is not possible to modify this value while the watchdog is running.
)
dec
Watchdog trigger, WD_TRIGGER
Read/write
0x0000
This register is used for an alternative trigger method. The watchdog is triggered
by writing different values in this register. Values following each other must differ
in size. Writing of a value not equal to zero starts the watchdog after a Power-on.
For a restart the written value must necessarily be unequal the before written
value! A watchdog fault is reset and writing process data is possible again.
)
dez
Minimum current trigger time, WD_AC_TRG_TIME
Read
0xFFFF
This register saves the minimum current watchdog trigger time. If the watchdog is
triggered, the saved value is compared with the current value. If the current value
is smaller than the saved value, this is replaced by the current value. The unit is
100 ms/digit. The saved value is changed by writing new values, which does not
affect the watchdog. 0x0000 is not permissible.
)
dez
Stop watchdog, WD_AC_STOP_MASK
Read/write
0x0000
The watchdog is stopped if here the value 0xAAAA is written first, followed by
0x5555. The watchdog fault reaction is blocked. A watchdog fault is reset and
writing on the process data is possible again.
