Match or Capture Channel x Event Output Enable [x = 1..0]
These bits enable the generation of an event for every match or capture on channel x.
Value | Description |
---|---|
0 | Match/Capture event on channel x is disabled and will not be generated. |
1 | Match/Capture event on channel x is enabled and will be generated for every compare/capture. |
Overflow/Underflow Event Output Enable
This bit enables the Overflow/Underflow event. When enabled, an event will be generated when the counter overflows/underflows.
Value | Description |
---|---|
0 | Overflow/Underflow event is disabled and will not be generated. |
1 | Overflow/Underflow event is enabled and will be generated for every counter overflow/underflow. |
TC Event Enable
This bit is used to enable asynchronous input events to the TC.
Value | Description |
---|---|
0 | Incoming events are disabled. |
1 | Incoming events are enabled. |
TC Inverted Event Input Polarity
This bit inverts the asynchronous input event source.
Value | Description |
---|---|
0 | Input event source is not inverted. |
1 | Input event source is inverted. |
Event Action
These bits define the event action the TC will perform on an event.
Value | Name | Description |
---|---|---|
0x0 | OFF | Event action disabled |
0x1 | RETRIGGER | Start, restart or retrigger TC on event |
0x2 | COUNT | Count on event |
0x3 | START | Start TC on event |
0x4 | STAMP | Time stamp capture |
0x5 | PPW | Period captured in CC0, pulse width in CC1 |
0x6 | PWP | Period captured in CC1, pulse width in CC0 |
0x7 | PW | Pulse width capture |
