CCMR1_in register
| CC1S | CC1S: Capture/Compare 1 Selection This bit-field defines the direction of the channel (input/output) as well as the used input. 00: CC1 channel is configured as output 01: CC1 channel is configured as input, IC1 is mapped on TI1 1x: Reserved Note: CC1S bits are writable only when the channel is OFF (CC1E = ‘0’ in TIMx_CCER). |
| IC1PSC | IC1PSC: Input capture 1 prescaler This bit-field defines the ratio of the prescaler acting on CC1 input (IC1). The prescaler is reset as soon as CC1E=‘0’ (TIMx_CCER register). 00: no prescaler, capture is done each time an edge is detected on the capture input. 01: capture is done once every 2 events 10: capture is done once every 4 events 11: capture is done once every 8 events |
| IC1F | Bits 7:4 IC1F[3:0]: Input capture 1 filter This bit-field defines the frequency used to sample TI1 input and the length of the digital filter applied to TI1. The digital filter is made of an event counter in which N events are needed to validate a transition on the output: 0000: No filter, sampling is done at fDTS 0001: fSAMPLING=fCK_INT, N=2 0010: fSAMPLING=fCK_INT, N=4 0011: fSAMPLING=fCK_INT, N=8 0100: fSAMPLING=fDTS/2, N= 0101: fSAMPLING=fDTS/2, N=8 0110: fSAMPLING=fDTS/4, N=6 0111: fSAMPLING=fDTS/4, N=8 1000: fSAMPLING=fDTS/8, N=6 1001: fSAMPLING=fDTS/8, N=8 1010: fSAMPLING=fDTS/16, N=5 1011: fSAMPLING=fDTS/16, N=6 1100: fSAMPLING=fDTS/16, N=8 1101: fSAMPLING=fDTS/32, N=5 1110: fSAMPLING=fDTS/32, N=6 1111: fSAMPLING=fDTS/32, N=8 |
| CC2S | CC2S: Capture/Compare 2 selection This bit-field defines the direction of the channel (input/output) as well as the used input. 00: CC2 channel is configured as output 01: CC2 channel is configured as input, IC2 is mapped on TI2 10: CC2 channel is configured as input, IC2 is mapped on TI1 11: CC2 channel is configured as input, IC2 is mapped on TRC. This mode is working only if an internal trigger input is selected through TS bit (TIMx_SMCR register) Note: CC2S bits are writable only when the channel is OFF (CC2E = ‘0’ in TIMx_CCER). |
