22.3.15 Error Channel Connections
The subsystems that can generate an error are connected to the ERRCTRL channels, as described
in the table below. The CRITICAL Recommended column identifies which errors are
typically recommended to be configured with critical severity. The channels may be configured
differently depending on application needs.
| Channel Number | Name | Peripheral | Source | Error | CRITICAL Recommended |
