Timer characteristics

The parameters given in Table 101 are guaranteed by design.

Refer to Section 6.3.15: I/O port characteristics for details on the input/output alternate

function characteristics (output compare, input capture, external clock, PWM output).

Table 101. TIMx characteristics(1)(2)

1. TIMx is used as a general term to refer to the TIM1 to TIM17 timers.

2. Guaranteed by design.

Parameter

Conditions(3)

3. The maximum timer frequency on APB1 or APB2 is up to 200 MHz, by setting the TIMPRE bit in the

RCC_CFGR register, if APBx prescaler is 1 or 2 or 4, then TIMxCLK = rcc_hclk1, otherwise TIMxCLK = 4x

Frcc_pclkx_d2.
