Field
ATOM Channel Slope Selection 1. The TSS1 field selects the slope for the ATOM selected channel.
00 Any transition (both)
29–28
01 Transition from 0 to 1 (positive slope)
TSS1
10 Transition from 1 to zero (negative slope)
11 Reserved
ATOM sub-module Source Selection 1. Selects which ATOM sub-module is the source for
watchpoint generation.

Halt Enable 1. The HEN1 Halt Enable 1 bit controls if the selected ATOM Channel is used to halt
the GTM module. If this bit is set and an event occurs on the selected ATOM Channel filter output,
23
a Halt 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 ATOM 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.
0 Watchpoint Messages disabled
1 Watchpoint Messages enabled
ATOM channel selection 1. Selects which channel in an ATOM module generates watchpoints.
000 ATOM CH0
001 ATOM CH1
010 ATOM CH2
18–16
011 ATOM CH3
CHSEL1
100 ATOM CH4
101 ATOM CH5
110 ATOM CH6
111 ATOM CH7
ATOM Channel Slope Selection 2. The TSS2 field selects the slope for the ATOM selected channel.
00 Any transition (both)
13–12
01 Transition from 0 to 1 (positive slope)
TSS2
10 Transition from 1 to zero (negative slope)
