IWDG prescaler register
PR | Prescaler divider These bits are write access protected, see Section126.4.6. They are written by software to select the prescaler divider feeding the counter clock. PVU bit of the IWDG status register (IWDG_SR) must be reset to be able to change the prescaler divider. Others: divider / 1024 Note: Reading this register returns the prescaler value from the VDD voltage domain. This value may not be up to date/valid if a write operation to this register is ongoing. For this reason the value read from this register is valid only when the PVU bit in the IWDG status register (IWDG_SR) is reset. 0 (B_0x0): divider / 4 1 (B_0x1): divider / 8 2 (B_0x2): divider / 16 3 (B_0x3): divider / 32 4 (B_0x4): divider / 64 5 (B_0x5): divider / 128 6 (B_0x6): divider / 256 7 (B_0x7): divider / 512 |
