Capture/Compare Unit 6 (CCU6)

Five further capture modes are called Multi-Input Capture Modes, as they use two different external inputs,

signal CC6xIN and signal CCPOSx.

Figure 139 Multi-Input Capture Modes Block Diagram

In each of these modes, the current T12 contents are captured in register CC6xR in response to a selected

event at signal CC6xIN, and in register CC6xSR in response to a selected event at signal CCPOSx. The possible

events can be opposite input transitions, or the same transitions, or any transition at the two inputs. The

different options are detailed in

In each of the various capture modes, the Channel State Bit, CC6xST, is set to 1 when the selected capture

trigger event at signal CC6xIN or CCPOSx has occurred. The State Bit is not cleared by hardware, but can be

cleared by software.

In addition, appropriate signal lines to the interrupt logic are activated, that can generate an interrupt request

to the CPU. Regardless of the selected active edge, all edges detected at signal CC6xIN can lead to the

activation of the appropriate interrupt request line (see also
