Explanation of function and operation
1. 16-bit operation (PR)
ASCII codes stored in low-order 8 bits (1 byte) of to +7 are output to to +7 in turn by
one character at a time in the time division method.
The timing chart below shows a case in which the following ASCII codes are stored in to +7.
Eight bytes are sent from = "A" at first to " +7 = "H" at the end.
