- "00H" indicating the end of a character string is automatically stored at the end of a converted character
string.
When the number of all digits is even, "0000H" is stored in the device after the last character.
When the number of all digits is odd, "00H" is stored in the high-order byte (8 bits) of the device storing
the final character.
