Port D shares two of its pins with TIM1 and port E shares two of its pins
with TIM2. The ADC12/T2CLK pin is an external clock input to TIM2. The
four TIM channel I/O pins are T1CH0, T1CH1, T2CH0, and T2CH1.
ADC12/T2CLK is an external clock input that can be the clock source for
the TIM2 counter instead of the prescaled internal bus clock. Select the
ADC12/T2CLK input by writing logic 1’s to the three prescaler select bits,
PS[2:0]. (See
T2CLK pulse width, T2CLK
The maximum T2CLK frequency is:
ADC12/T2CLK is available as a ADC input channel pin when not used
as the TIM2 clock input.
Each channel I/O pin is programmable independently as an input
capture pin or an output compare pin. T1CH0 and T2CH0 can be
configured as buffered output compare or buffered PWM pins.
