GTM sub-module generates two watchpoints which can be routed internally to the GTMDI
and generate watchpoint triggers or routed to the message formatter and generate
watchpoint messages. The selection between watchpoint triggers and messages is
implemented per sub-module. Messages and watchpoint triggers can also be generated at
the same time based on the same event within a sub-module, thus a TIM channel transition
can generate a watchpoint trigger and a watchpoint message. The watchpoint triggers may
be sent to the Sequence Processing Unit (SPU) outside the GTMDI if enabled by
appropriate control register bits for each sub-module, such as Timer Input Module (TIM),
Timer Output Module (TOM) and ARU-connected Timer Output Module (ATOM). The
watchpoint messages, if enabled, are sent to the NAR through the Nexus Client interface.
