General-purpose timers (TIM16/TIM17)
Bits 1:0 CC1S[1:0]: 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
Others: Reserved
Note: CC1S bits are writable only when the channel is OFF (CC1E = '0' in TIMx_CCER).
27.4.7 TIMx capture/compare mode register 1 [alternate]
(TIMx_CCMR1)(x = 16 to 17)
Address offset: 0x18
Reset value: 0x0000 0000
The same register can be used for output compare mode (this section) or for input capture
mode (previous section). The direction of a channel is defined by configuring the
corresponding CCxS bits. All the other bits of this register have a different function in input
and in output mode.
