Watchdog counter window value These bits are write access protected, see , they contain the high limit of the window value to be compared with the downcounter. To prevent a reset, the downcounter must be reloaded when its value is lower than the window register value and greater than 0x0 The WVU bit in the must be reset in order to be able to change the reload value. Note: Reading this register returns the reload value from the VDD voltage domain. This value may not be valid if a write operation to this register is ongoing. For this reason the value read from this register is valid only when the WVU bit in the (IWDG_SR) is reset.
