I have ST72264 SCI protocol question. This is copied from Datasheet:

Bit TC is cleared by a software sequence (an access to the

SCISR register followed by a write to the SCIDR register).

My question:

Is it necessary that these two instructions are followed directly each by other or is it possible to insert some other instruction(s) in between?

Thank you.
