Watchpoint Trigger Output Selection 1. The WTSEL1[2:0] field selects among 8 available
watchpoint triggers which one is connected to the ARU Debugging Channel 0. Other modules can
selected the same WTSEL1 value, in this case the result selection is an OR of all selected sources.

TEN1 0 Disable Trigger Generation
1 Enable Trigger Generation
Start/Stop Enable 1. The SEN1 bit field enable the ARU Debugging Channel 0 to consider the
Start/Stop inputs for watchpoint trace message generation. If this bit is cleared, the messages are
