Bits [31:8]

Bit 7

Selects the GPIO used for TIM2_CH4: 0 = PA2, 1 = PB4

Bit 6

Selects the GPIO used for TIM2_CH3: 0 = PA1, 1 = PB3

Bit 5

Selects the GPIO used for TIM2_CH2: 0 = PA3, 1 = PB2

Bit 4

Selects the GPIO used for TIM2_CH1: 0 = PA0, 1 = PB1

Bit 3

Reserved: this bit must always be set to 0

Bit 2

Enables TIM2MSK when TIM2CLK is selected as the external trigger: 0 = TIM2MSK not

used, 1 = TIM2CLK is ANDed with the TIM2MSK input.

Bits [1:0]

Selects the external trigger used in external clock mode 2: 0 = PCLK, 1 = calibrated 1 kHz

clock, 2 = 32 kHz reference clock (if available), 3 = TIM2CLK pin.
