Bits [31:7]

Bit 6

0: Does nothing

1: Sets the TIM_TIF flag in the TIMx_SR register

Bit 5

Bit 4

0: Does nothing

1: If CC4 configured as output channel, the CC4IF flag is set. If CC4 configured as input

channel, the CC4IF flag is set. The CC4IM flag is set if the CC4IF flag was already high. The

current value of the counter is captured in TIMx_CCR4 register.

Bit 3

0: Does nothing

1: If CC3 configured as output channel, the CC3IF flag is set. If CC3 configured as input

channel, the CC3IF flag is set. The CC3IM flag is set if the CC3IF flag was already high. The

current value of the counter is captured in TIMx_CCR3 register.

Bit 2

0: Does nothing

1: If CC2 configured as output channel, the CC2IF flag is set. If CC2 configured as input

channel, the CC2IF flag is set. The CC2IM flag is set if the CC2IF flag was already high. The

current value of the counter is captured in TIMx_CCR2 register.

Bit 1

0: Does nothing

1: If CC1 configured as output channel, the CC1IF flag is set. If CC1 configured as input

channel, the CC1IF flag is set. The CC1IM flag is set if the CC1IF flag was already high. The

current value of the counter is captured in TIMx_CCR1 register.

Bit 0

0: Does nothing

1: Re-initializes the counter and generates an update of the registers. This also clears the

prescaler counter but the prescaler ratio is not affected. The counter is cleared if center-

aligned mode is selected or if DIR=0 (up-counting), otherwise it takes the auto-reload value

(TIM1_ARR) if DIR=1 (down-counting).
