Description:
Trigger command
Address:
0x40000220
Offset:
0x220
Retention:
Not Retained
IsDeepSleep:
No
Comment:
This register provides SW control over trigger activation. This is useful for SW initiated triggers
(e.g. DW/DMA transfers) or for debugging purposes. The control enables SW activation of one
specific input trigger or output trigger of the trigger multiplexer structure.

Description

TR_SEL
RW
R
0
Specifies the activated trigger when ACTIVATE is '1'. If
the specified trigger is not present, the trigger
activation has no effect.
8:12
GROUP_SEL
RW
R
0
Specifies the trigger group:
'0'-'15': trigger multiplexer groups.
'16'-'31': trigger 1-to-1 groups.
29
TR_EDGE
RW
R
0
Specifies if the activated trigger is treated as a level
sensitive or edge sensitive trigger.
'0': level sensitive. The trigger reflects
TR_CMD.ACTIVATE.
'1': edge sensitive trigger. The trigger is activated for
two clk_peri cycles.
30
OUT_SEL
RW
R
0
Specifies whether trigger activation is for a specific
input or output trigger of the trigger multiplexer.
Activation of a specific input trigger, will result in
activation of all output triggers that have the specific
input trigger selected through their
TR_OUT_CTL.TR_SEL field. Activation of a specific
output trigger, will result in activation of the specified
TR_SEL output trigger only.
'0': TR_SEL selection and trigger activation is for an
input trigger to the trigger multiplexer.
'1': TR_SEL selection and trigger activation is for an
output trigger from the trigger multiplexer.
Note: this field is not used for trigger 1-to-1 groups.
