Trigger MUX Control (TRGMUX)
10.1 Chip-specific information for this module
10.1.1 Module Interconnectivity
The module interconnectivity scheme is based on the TRGMUX. The TRGMUX
introduces an extremely flexible methodology for connecting various trigger sources to
multiple pins/peripherals. This TRGMUX design has removed some trigger inputs, and
added one pre-stage trigger source TRGMUX1 for the TRGMUX0. TRGMUX1 supports
up to 32 trigger sources and has 8 outputs. These 8 outputs will be the trigger inputs of
TRGMUX0. TRGMUX0 supports up to 32 input sources, and its output will be the target
modules.
With the TRGMUX, each peripheral which accepts external triggers will usually have
one specific 32-bit trigger control register. Each control register supports up to 4 triggers,
and each trigger can be selected from up to 32 inputs.
For some trigger sources, there is optional pre-trigger. The trigger and the pre-trigger are
1-1 paired up, and are both selected by the same trigger control register. Not every
module has pre-trigger input, please refer to the respective module chapter for details.
Following is the main structure of TRGMUX, and take ModuleA as an example.
