Bit 15 – ONDEMAND Generic Clock On Demand
| Value | Description |
|---|---|
| 0 | Generic clock for a channel is always on, if the channel is configured and generic clock source is enabled. |
| 1 | Generic clock is requested on demand while an event is handled |
Bit 14 – RUNSTDBY Run in Standby
This bit is used to define the behavior during standby sleep mode.
| Value | Description |
|---|---|
| 0 | The channel is disabled in standby sleep mode. |
| 1 | The channel is not stopped in standby sleep mode and depends on the CHANNEL.ONDEMAND |
Bits 11:10 – EDGSEL[1:0] Edge Detection Selection
These bits set the type of edge detection to be used on the channel.
These bits must be written to zero when using the asynchronous path.
| Value | Name | Description |
|---|---|---|
| 0x0 | NO_EVT_OUTPUT | No event output when using the resynchronized or synchronous path |
| 0x1 | RISING_EDGE | Event detection only on the rising edge of the signal from the event generator |
| 0x2 | FALLING_EDGE | Event detection only on the falling edge of the signal from the event generator |
| 0x3 | BOTH_EDGES | Event detection on rising and falling edges of the signal from the event generator |
Bits 9:8 – PATH[1:0] Path Selection
These bits are used to choose which path will be used by the selected channel.
The path choice can be limited by the channel source, see the table in USERm29.8.8 Event User m.
| Value | Name | Description |
|---|---|---|
| 0x0 | SYNCHRONOUS | Synchronous path |
| 0x1 | RESYNCHRONIZED | Resynchronized path |
| 0x2 | ASYNCHRONOUS | Asynchronous path |
| 0x3 | - | Reserved |
Bits 6:0 – EVGEN[6:0] Event Generator
These bits are used to choose the event generator to connect to the selected channel.
| Value | Event Generator | Description |
|---|---|---|
| 0x00 | NONE | No event generator selected |
