+All clock prescalers managed by RCC can be controlled with a single
+function, ``rcc_set_prescaler()``.
.. doxygenfunction:: rcc_set_prescaler
The arguments to ``rcc_set_prescaler()`` are target-dependent, but
-follow a common pattern.
-
-The first argument specifies the prescaler to set. Each target has a
-corresponding ``rcc_prescaler`` type. Prescalers which are common
-across targets have the same token, though not necessarily the same
-value, for their ``rcc_prescaler`` (for example,
-``RCC_PRESCALER_APB1`` is available on both STM32F1 and STM32F2
-targets).
-
-The second argument determines the divider; it is chosen based on the
-prescaler chosen in the first argument. Along with each prescaler,
-there is a separate enum type listing all of the available clock
-dividers corresponding to that prescaler. For example, on STM32F1, the
-corresponding dividers for ``RCC_PRESCALER_APB1`` are given by the
-``rcc_apb1_divider`` type. It has values like ``RCC_APB1_HCLK_DIV_1``,
-``RCC_APB1_HCLK_DIV_2``, etc. In general, the dividers for
-``RCC_PRESCALER_FOO`` are given by the type ``rcc_foo_divider``.
-
-The available prescalers and dividers on each supported target series
-are as follows.
+follow a common pattern:
+
+- The first argument is the prescaler to set, so there's one for each
+ peripheral clock domain, etc. These have names like
+ ``RCC_PRESCALER_FOO``, e.g. ``RCC_PRESCALER_APB1``. Choose the
+ prescaler from the ``rcc_prescaler``\ s on your target (see below).
+
+- The second argument is the actual clock divider to use; it's chosen
+ based on the first argument. The dividers for ``RCC_PRESCALER_FOO``
+ are given by the type ``rcc_foo_divider``, and have values like
+ ``RCC_FOO_xxx_DIV_y``. This means that the foo clock will be the
+ ``xxx`` clock divided by ``y``.
+
+For example, calling ``rcc_set_prescaler(RCC_PRESCALER_APB1,
+RCC_APB1_HCLK_DIV_1)`` would set the APB1 clock to HCLK divided by 1.
+
+Prescalers which are common across targets have the same token, though
+not necessarily the same value, for their ``rcc_prescaler`` (for
+example, ``RCC_PRESCALER_APB1`` is available on both STM32F1 and
+STM32F2 targets). The available prescalers and dividers on each
+supported target series are as follows.
