General-purpose timer block diagram

Note:

The internal signals shown in Figure 10 are described in Section 8.1.15: Timer signal

descriptions on page 110 and are used throughout the text to describe how the timer

components are interconnected.

8.1

Functional description

The timers can optionally use GPIOs in the PA and PB ports for external inputs or outputs.

As with all STM32W108 digital inputs, a GPIO used as a timer input can be shared with

other uses of the same pin. Available timer inputs include an external timer clock, a clock

mask, and four input channels. Any GPIO used as a timer output must be configured as an

alternate output and is controlled only by the timer.

Many of the GPIOs that can be assigned as timer outputs can also be used by another on-

chip peripheral such as a serial controller. Use as a timer output takes precedence over

another peripheral function, as long as the channel is configured as an output in the

TIMx_CCMR1 register and is enabled in the TIMx_CCER register.
