2. Next, write the desired value to the sub element tag in question. The sub element tag immediately takes

on the value written to it.

Note: After a sub element is written to at least once in block write mode, the tag's value does not originate

from the controller, but instead from the driver's write cache. After the block write is done, all sub

element tag values originate from the controller.

3. Once the entire desired sub elements are written to, perform the block write that sends these values to

the controller. To instantiate a block write, reference tag address RTC:<element>._SET. Setting this tag's

value to 'true' causes a block write to occur based on the current (last read) sub elements and the sub

elements affected (written to). Immediately after setting the tag to 'true', it is automatically reset to

"false." This is the default state and performs no action.
