Description:
MCWDT Subcounter Configuration Register
Address:
0x40268010
Offset:
0x10
Retention:
Retained
IsDeepSleep:
No
Comment:
Configuration for this MCWDT subcounter. Writes are ignored when locked (i.e. corresponding
MCWDT[i]_LOCK.WDT_LOCK<>0). This register may be written while the counter is running,
but new values may take up to 2 clk_lf cycles to take effect. MCWDT always reports the first
fault that occurs across subcounter #0 and subcounter #1 for this MCWDT, but may not report
additional faults that occur while the first is being processed.
Default:
0x0

Description
0:1 LOWER_ACTION RW R 0 Action taken if this watchdog is serviced before
LOWER_LIMIT is reached. LOWER_ACTION is
ignored (i.e. treated as NOTHING) when a debugger is
connected and/or when the corresponding processor is
in SLEEPDEEP.
NOTHING 0 Do nothing
FAULT 1 Trigger a fault. It can take up to 3 clk_lf cycles for the
fault to be transferred to the fault manager.
For LOWER_LIMIT >= 1: The action is triggered on
same edge when it meets this condition.
For LOWER_LIMIT == 0: No action is triggered.
FAULT_THEN_RESET 2 Trigger a fault. Further, trigger a system-wide reset if
the fault is not serviced and the watchdog is not
cleared within 6 clk_lf cycles. It can take up to 3 clk_lf
cycles for the fault to be transferred to the fault
manager, which gives at least 3 clk_lf cycles for
software to respond.
For LOWER_LIMIT >= 1: The action is triggered on
same edge when it meets this condition.
For LOWER_LIMIT == 0: No action is triggered.
4:5 UPPER_ACTION RW R 0 Action taken if this watchdog is not serviced before
UPPER_LIMIT is reached. The counter stops counting
when UPPER_LIMIT is reached, regardless of
UPPER_ACTION setting. UPPER_ACTION is ignored
(i.e. treated as NOTHING) when a debugger is
connected.
NOTHING 0 Do nothing
