Prescaler register
| PR | Prescaler divider These bits are write access protected see . They are written by software to select the prescaler divider feeding the counter clock. PVU bit of the must be reset in order to be able to change the prescaler divider. 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 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 /256 |
