General-purpose timer (TIMx)
366/995
Bits 7:4 IC1F: Input capture 1 filter
Bits 3:2 IC1PSC: Input capture 1 prescaler
Bits 1:0 CC1S: Capture/Compare 1 selection
Note: In current silicon revision, f
Note: CC1S bits are writable only when the channel is OFF (CC1E = ’0’ in TIMx_CCER).
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 f

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.
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.
10: CC1 channel is configured as input, IC1 is mapped on TI2.
11: CC1 channel is configured as input, IC1 is mapped on TRC. This mode is working only if
an internal trigger input is selected through TS bit (TIMx_SMCR register)
1, 2 or 3.
