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 ATOM Channel. Other modules can
select the same WTSEL1 value, in this case the result watchpoint signal implements an OR of all
selected sources.

Start/Stop input signal selection 1. Selects the Start/Stop input that is used to control the watchpoint
trace messages. These signals are actually a pair of signals.

1 Enable Trigger Generation
Start/Stop Enable 1. The SEN1 bit field enables the selected ATOM channel to consider the
Start/Stop inputs for watchpoint trace messages control. If this bit is cleared, the messages are

controlled only by JTAG writes to the WMC1 field in the GTMDI_ATOM_WPC1 register.
