Explanation:
1. Refer to the execution of SOPEN instruction for relative setups and examples for the
transmission length with 4 Words.
2. Using the flags for sending an odd number of characters will take 1 byte and thus the actual
transmission will be 7 Bytes. For transmission without using the flags for sending an odd
number of characters, the actual transmission will be 8 Bytes.
