General-purpose timers
158/232
Bits [14:12] TIM_OC2M: Output Compare 2 Mode. (Applies only if TIM_CC2S = 0
Bit 11 TIM_OC2BE: Output Compare 2 Buffer Enable. (Applies only if TIM_CC2S = 0
Bit 10 TIM_OC2FE: Output Compare 2 Fast Enable. (Applies only if TIM_CC2S = 0)
Define the behavior of the output reference signal OC2REF from which OC2 derives. OC2REF
is active high whereas OC2''s active level depends on the TIM_CC2P bit.
000: Frozen - The comparison between the output compare register TIMx_CCR2 and the
counter TIMx_CNT has no effect on the outputs.
001: Set OC2REF to active on match. The OC2REF signal is forced high when the counter
TIMx_CNT matches the capture/compare register 2 (TIMx_CCR2)
010: Set OC2REF to inactive on match. OC2REF signal is forced low when the counter
TIMx_CNT matches the capture/compare register 2 (TIMx_CCR2).
011: Toggle - OC2REF toggles when TIMx_CNT = TIMx_CCR2.
100: Force OC2REF inactive.
101: Force OC2REF active.
110: PWM mode 1 - In up-counting, OC2REF is active as long as TIMx_CNT < TIMx_CCR2,
otherwise OC2REF is inactive. In down-counting, OC2REF is inactive if
TIMx_CNT > TIMx_CCR2, otherwise OC2REF is active.
111: PWM mode 2 - In up-counting, OC2REF is inactive if TIMx_CNT < TIMx_CCR2, otherwise
OC2REF is active. In down-counting, OC2REF is active if TIMx_CNT > TIMx_CCR2, otherwise
it is inactive.
Note: In PWM mode 1 or 2, the OC2REF level changes only when the result of the
0: Buffer register for TIMx_CCR2 is disabled. TIMx_CCR2 can be written at anytime, the new
value is used by the shadow register immediately.
1: Buffer register for TIMx_CCR2 is enabled. Read/write operations access the buffer register.
TIMx_CCR2 buffer value is loaded in the shadow register at each update event.
Note: The PWM mode can be used without enabling the buffer register only in one pulse mode
This bit speeds the effect of an event on the trigger in input on the OC2 output.
0: OC2 behaves normally depending on the counter and TIM_CCR2 values even when the
trigger is ON. The minimum delay to activate OC2 when an edge occurs on the trigger input is 5
clock cycles.
1: An active edge on the trigger input acts like a compare match on the OC2 output. OC2 is set
to the compare level independently from the result of the comparison. Delay to sample the
trigger input and to activate OC2 output is reduced to 3 clock cycles. TIM_OC2FE acts only if
the channel is configured in PWM 1 or PWM 2 mode.
comparison changes or when the output compare mode switches from “frozen” mode to
“PWM” mode.
(TIM_OPM bit set in the TIMx_CR2 register), otherwise the behavior is undefined.
