IWDG window register
WIN | Watchdog counter window value These bits are write access protected, see Section126.4.6.They contain the high limit of the window value to be compared with the downcounter. To prevent a reset, the IWDCNT downcounter must be reloaded when its value is lower than WIN[11:0]1+11 and greater than 1. The WVU bit in the IWDG status register (IWDG_SR) must be reset 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 status register (IWDG_SR) is reset. |
