Example 2-3: As same as the Query in example 2-1, this query sets 3000sec to Acceleration time (1) (F002,
register number = 1103h). But the data resolution of this Holding register is 0.01sec, so the data to be
written is 300000d = 000493E0h.
Compared with Example 2-1 in which Big Endian is used, this Special Endian example swaps data in high
order (2bytes) and low order (2 bytes).
Query:
Notice the data from eighth to eleventh.
Write data (Change data 1, 2) are subject to the Endian function.
(As for the data arrangements of Special Endian, please refer to "[2] How data are arranged by each
endian.")
