Timer 1 Capture/Compare Mode Register 2
TIM2_CCMR2
Timer 2 Capture/Compare Mode Register 2
Timer channels can be programmed as inputs (capture mode) or outputs (compare mode). The direction of channel y is defined by TIM_CCyS in this
register.
The other bits in this register have different functions in input and in output modes. The TIM_OC* fields only apply to a channel configured as an
output (TIM_CCyS = 0), and the TIM_IC* fields only apply to a channel configured as an input (TIM_CCyS > 0).

Description
Output Compare 4 Mode. (Applies only if TIM_CC4S = 0.)
Define the behavior of the output reference signal OC4REF from which OC4 derives.
OC4REF is active high whereas OC4’s active level depends on the TIM_CC4P bit.
000: Frozen - The comparison between the output compare register TIMx_CCR4 and the
counter TIMx_CNT has no effect on the outputs.
001: Set OC4REF to active on match. The OC4REF signal is forced high when the counter
TIMx_CNT matches the capture/compare register 4 (TIMx_CCR4)
010: Set OC4REF to inactive on match. OC4REF signal is forced low when the counter
TIMx_CNT matches the capture/compare register 4 (TIMx_CCR4).
011: Toggle - OC4REF toggles when TIMx_CNT = TIMx_CCR4.
100: Force OC4REF inactive.
101: Force OC4REF active.
110: PWM mode 1 - In up-counting, OC4REF is active as long as TIMx_CNT < TIMx_CCR4,
otherwise OC4REF is inactive. In down-counting, OC4REF is inactive if
TIMx_CNT > TIMx_CCR4, otherwise OC4REF is active.
111: PWM mode 2 - In up-counting, OC4REF is inactive if TIMx_CNT < TIMx_CCR4,
otherwise OC4REF is active. In down-counting, OC4REF is active if TIMx_CNT > TIMx_CCR4,
otherwise it is inactive.
Note: In PWM mode 1 or 2, the OC4REF level changes only when the result of the
comparison changes or when the output compare mode switches from “frozen” mode to
“PWM” mode.
Output Compare 4 Buffer Enable. (Applies only if TIM_CC4S = 0.)
0: Buffer register for TIMx_CCR4 is disabled. TIMx_CCR4 can be written at anytime, the
new value is used by the shadow register immediately.
1: Buffer register for TIMx_CCR4 is enabled. Read/write operations access the buffer
register. TIMx_CCR4 buffer value is loaded in the shadow register at each UEV.
Note: The PWM mode can be used without enabling the buffer register only in one pulse
mode (TIM_OPM bit set in the TIMx_CR2 register), otherwise the behavior is undefined.
