l3warmmask
The L3WARMMASK register is used by software to mask the assertion of module reset signals for hardware sequenced warm resets. There is a writeable bit for each module reset signal that is asserted by default on a hardware sequenced warm reset. If the bit is 1, the module reset signal is asserted by a hardware sequenced warm reset. If the bit is 0, the module reset signal is not changed by a hardware sequenced warm reset. The bit assignments of the *WARMMASK registers match the corresponding *MODRST registers. Any module reset signals that are never asserted by a warm reset have reserved bit offsets and are tied to 0 (read as 0, writes are ignored).
All fields are only reset by a cold reset.
Note that there is no module reset for the L3 interconnect in any *MODRST register because there would be no way for a master to remove the module reset to the L3 once asserted.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
