Halt Enable 1. The HEN1 Halt Enable 1 bit controls if the selected TOM Channel is used to halt the
GTM module. If this bit is set and an event occurs on the selected TOM Channel filter output, a Halt
23
signal is generated to the GTM which enters debug state.
HEN1
0 Disables Halt GTM
1 Enables Halt GTM
Watchpoint Message Control 1. The WMC1 Watchpoint Message Control 1 bit controls the
watchpoint message sent through the Message Data bus. If this bit is set it enables valid transitions
on the selected TOM Channel output to generate a watchpoint message. This bit is written by the
22
JTAG interface but can also be controlled at SoC level with dedicated Start/Stop signals inputs to
WMC1
GTMDI.
