IWDG window register
WIN | Watchdog counter window value These bits are write access protected, see Section 22.3.4, 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 IWDG status register (IWDG_SR) 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 status register (IWDG_SR) is reset. |
