In this example, the following 26-byte text string is received: ABCDEFGHIJKLMNOPQRSTUVWXYZ.
The text string is separated into
the first 20 bytes (ABCDEFGHIJKLMNOPQRST) and the remaining 6
bytes (UVWXYZ) to send it from the CIF Unit to the CPU Unit or communications master.
It is assumed that the Number of Characters to Determine the End is set
as the condition to determine
the reception completion.
For a programming sample for this example, refer to A-4-4 Programming Sample 3: Receiving Data on
