IMPORTANT
•To ensure stable data input, assign a data input interval of approximately one
second. A shorter interval may result in a data error. If an error results, an
appropriate error handling procedure must be executed in a program.
•A few seconds of power accumulation time is required before starting data input.
CAUTION
d1~d13 are respectively represent one byte.
