TIM15 control register 2
| CCPC | Capture/compare preloaded control 0 (B_0x0): CCxE, CCxNE and OCxM bits are not preloaded 1 (B_0x1): CCxE, CCxNE and OCxM bits are preloaded, after having been written, they are updated only when a commutation event (COM) occurs (COMG bit set or rising edge detected on tim_trgi, depending on the CCUS bit). |
| CCUS | Capture/compare control update selection 0 (B_0x0): When capture/compare control bits are preloaded (CCPC=1), they are updated by setting the COMG bit only. 1 (B_0x1): When capture/compare control bits are preloaded (CCPC=1), they are updated by setting the COMG bit or when an rising edge occurs on tim_trgi. |
| CCDS | Capture/compare DMA selection 0 (B_0x0): CCx DMA request sent when CCx event occurs 1 (B_0x1): CCx DMA requests sent when update event occurs |
| MMS | Master mode selection 0 (B_0x0): Reset - the UG bit from the TIM15_EGR register is used as trigger output (tim_trgo). If the reset is generated by the trigger input (slave mode controller configured in reset mode) then the signal on tim_trgo is delayed compared to the actual reset. 1 (B_0x1): Enable - the Counter Enable signal CNT_EN is used as trigger output (tim_trgo). It is useful to start several timers at the same time or to control a window in which a slave timer is enable. The Counter Enable signal is generated by a logic AND between CEN control bit and the trigger input when configured in gated mode. When the Counter Enable signal is controlled by the trigger input, there is a delay on tim_trgo, except if the master/slave mode is selected (see the MSM bit description in TIM15_SMCR register). 2 (B_0x2): Update - The update event is selected as trigger output (tim_trgo). For instance a master timer can then be used as a prescaler for a slave timer. 3 (B_0x3): Compare Pulse - The trigger output send a positive pulse when the CC1IF flag is to be set (even if it was already high), as soon as a capture or a compare match occurred (tim_trgo). 4 (B_0x4): Compare - tim_oc1refc signal is used as trigger output (tim_trgo). 5 (B_0x5): Compare - tim_oc2refc signal is used as trigger output (tim_trgo). |
| TI1S | tim_ti1 selection 0 (B_0x0): The tim_ti1_in[15:0] multiplexer output is connected to tim_ti1 input 1 (B_0x1): The tim_ti1_in[15:0] and tim_ti2_in[15:0] multiplexers output are connected to the tim_ti1 input (XOR combination) |
| OIS1 | Output Idle state 1 (tim_oc1 output) 0 (B_0x0): tim_oc1=0 after a dead-time when MOE=0 1 (B_0x1): tim_oc1=1 after a dead-time when MOE=0 |
| OIS1N | Output Idle state 1 (tim_oc1n output) 0 (B_0x0): tim_oc1n=0 after a dead-time when MOE=0 1 (B_0x1): tim_oc1n=1 after a dead-time when MOE=0 |
| OIS2 | Output idle state 2 (tim_oc2 output) 0 (B_0x0): tim_oc2=0 when MOE=0 1 (B_0x1): tim_oc2=1 when MOE=0 |
| ADSYNC | ADC synchronization 0 (B_0x0): The timer operates independently from the ADC 1 (B_0x1): The timer operation is synchronized with the ADC clock to provide jitter-free sampling point. This mode can be enabled only with specific ADC / timer clock relationship. Refer to Section 57.4.29 for requirements. |
