Description
Internal clock source: connects to EM35x peripheral clock (PCLK) in internal clock mode.
Input to the clock prescaler.
External trigger input (used in external timer mode 2): a clock selected by
TIM_EXTRIGSEL in TIMx_OR.
External trigger: ETRP after filtering.
External trigger: ETR after polarity selection, edge detection and prescaling.
Input capture signal after filtering, edge detection and prescaling: input to the capture
register.
Internal trigger input: connected to the other timer’s output, TRGO.
polarity inversion.
Output compare reference: always active high, but may be inverted to produce OCy.
12 MHz if using the 24 MHz crystal oscillator and 6 MHz if using the 12 MHz RC oscillator.
Timer input: TIMxCy when used as a timer input.
Timer input after filtering and polarity selection.
Timer channel at a GPIO pin: can be a capture input (ICy) or a compare output (OCy).
Trigger input for slave mode controller.
