*PREDIV1 Prescaler*

*PREDIV1 Prescaler*

Type: ``int``

Help
====

PREDIV1 is a PLL clock signal prescaler for any PLL input.
It is supported by STM32F04xx, STM32F07xx, STM32F09xx, STM32F030xC,
STM32F302xE, STM32F303xE and STM32F39xx parts.
If configured on a non-supported part, this config will be ignored.
Allowed values: 1 - 16.
