GTM Development Interface (GTMDI)
42.5.1.5 TIM watchpoint control register 2 (GTMDI_TIM_WPC2)
The GTMDI_TIM_WPC2 register shown in
WPT issued by TIM channels. These watchpoint triggers are used to control GTM Halt state
entering, watchpoint messages and control external logic to the GTMDI. See
details of the logic that uses the bits in this register.

Note: The SHARED_WPT and SHARED_WPT_ST signals mentioned in
tables in this document, refer to the GTMDI top level connections. They correspond to
Watchpoint trigger outputs of GTMDI and Stop/Start input signals respectively.
Field
Watchpoint Trigger Output Selection 1. The WTSEL1[2:0] bit field selects among 8 available output
Watchpoint triggers which one is connected to the selected TIM Channel. Other modules can select
the same WTSEL1 value, in this case the result watchpoint signal implements an OR of all selected
sources.
