28.6.23 TIMx capture/compare mode register 3
(TIMx_CCMR3)(x = 1, 8, 20)
Address offset: 0x050
Reset value: 0x0000 0000
Refer to the above CCMR1 register description. Channels 5 and 6 can only be configured in
output.
Bits 31:20 Reserved, must be kept at reset value.
Bits 19:0 CCR6[19:0]: Capture/compare 6 value
CCR6 is the value to be loaded in the actual capture/compare 6 register (preload value).
It is loaded permanently if the preload feature is not selected in the TIMx_CCMR3 register
(bit OC6PE). Else the preload value is copied in the active capture/compare 6 register when
an update event occurs.
The active capture/compare register contains the value to be compared to the counter
TIMx_CNT and signaled on tim_oc6 output.
Non-dithering mode (DITHEN = 0)
The register holds the compare value in CCR6[15:0]. The CCR6[19:16] bits are reset.
Dithering mode (DITHEN = 1)
The register holds the integer part in CCR6[19:4]. The CCR6[3:0] bitfield contains the
dithered part.
