WDG_ReadWindow
Unsigned char WDG_ReadWindow (void)
Returns the value of the window register
None
Window register value
None
None
None
WDG_WriteWindow
Void WDG_WriteWindow (unsigned char)
Loads the value of the window register which is compared
with the watchdog counter
Value to be loaded in the Window register. This value
must be between 0x00 and 0x7F
None
None
None
After this function, Watchdog counter value is compared
with the new window value. If watchdog counter is reload-
ed outside this window value, a watchdog reset is gener-
ated.
WDG_ReadCounter
Unsigned char WDG_ReadCounter (void)
Returns the WDG counter register value
None
WDG counter register value
None
None
None
