TRU Definitions
The following definitions are helpful when using the TRU module.
Trigger Master
A trigger master is any system module that provides trigger event indication to the TRU. Trigger master modules
define trigger events and conditions for assertion.
Trigger Master ID
Trigger masters are assigned a unique numeric ID according to their physical connection to the TRU. Trigger master
ID 0 is reserved and defined as null.
Trigger Slave
A trigger slave is any system module that receives a trigger event indication from the TRU. Trigger slave modules
define a trigger event response.
TRU Block Diagram
Trigger masters and the Master Trigger Register (MTR) generate trigger assertions. Each trigger slave has a dedicated
Slave Select Register (SSR) that specifies the unique trigger master from which it receives the trigger indication.
