Description
8
WARN_ACTION
RW
A
0
Action taken when the count value reaches
WARN_LIMIT. The minimum setting to achieve a
periodic interrupt is WARN_LIMIT==1. A setting of
zero will trigger once but not periodically.
For WARN_LIMIT >= 2: The action is triggered on
same edge when it meets this condition.
For WARN_LIMIT < 2 : The action may take up to one
extra clk_ilo0 cycle to trigger.
NOTHING
0
Do nothing
INT
1
Trigger an interrupt.
12
AUTO_SERVICE
RW
A
0
Automatically service when the count value reaches
WARN_LIMIT. This allows creation of a periodic
interrupt if this counter is not needed as a watchdog.
This field is ignored when
LOWER_ACTION<>NOTHING or when
UPPER_ACTION<>NOTHING.
28
DEBUG_TRIGGER_EN
RW
A
0
Enables the trigger input for WDT to pause the counter
during debug mode. To pause at a breakpoint while
debugging, configure the trigger matrix to connect the
related CPU halted signal to the trigger input for this
WDT, and then set this bit. It takes up to two clk_ilo0
cycles for the trigger signal to be processed. Triggers
that are less than two clk_ilo0 cycles may be missed.
Synchronization error can accumulate each time it is
halted.
0: Pauses the counter whenever a debug probe is
connected.
1: Pauses the counter whenever a debug probe is
connected and the trigger input is high.
29
DPSLP_PAUSE
RW
A
0
Pauses/runs this counter when the system is in
DEEPSLEEP. Note it may take up to two clk_ilo0
cycles for the counter to pause, due to internal
synchronization. During DEEPSLEEP wakeup, the
pause request is removed when clk_hf0 starts
clocking, and then it may take up to two clk_ilo0 cycles
for the counter to start. After wakeup, the
LOWER_ACTION is ignored until after the first service.
This prevents an unintentional trigger of the
LOWER_ACTION before the firmware realigns the
servicing period. After the first service,
LOWER_ACTION behaves as configured.
0: Counter behaves normally during DEEPSLEEP.
1: Counter pauses during DEEPSLEEP.
30
HIB_PAUSE
RW
A
0
Pauses/runs this counter when the system is in
HIBERNATE. Note it may take up to two clk_ilo0
cycles for the counter to pause, due to internal
synchronization. After wakeup, the LOWER_ACTION
is ignored until after the first service. This prevents an
unintentional trigger of the LOWER_ACTION before
the firmware realigns the servicing period. After the
first service, LOWER_ACTION behaves as configured.
0: Counter behaves normally during HIBERNATE.
1: Counter pauses during HIBERNATE.
