5.1.2. Block Read command：Indirect (03H)
Select the read data which is desired to be read in block communication to Block Communication
Read Data Parameters (f875 to f879). This parameter becomes effective when the system
is reset, such as when power is turned off. When the setting is completed, turn off and then on the
power.
