Register Description
CHnMUX – Event Channel n Multiplexer Register
.
• Bit 7:0 - CHnMUX[7:0]: Channel Multiplexer
These bits select the event source according to
devices regardless of if the peripheral is present or not. Selecting event sources from peripher-
als that are not present will give the same result as when this register is zero. When this register
is zero no events are routed through. Manually generated events will override the CHnMUX and
be routed to the event channel even if this register is zero.
