Instruction read
1. Transfer to the common driver must take place immediately after setting up the instruction.
2. The serial transfer period takes a maximum of 1/fosc x 18 clock cycles (sec).
3. Serial transfer cannot be executed in standby mode. If the chip enters standbymode during transfer,
the serial transfer is forcibly suspended. Transfer must be executed again because correct transfer is
not guaranteed in this situation.
correct transfer is not guaranteed in this situation.
Before executing, confirm that the transfer is completed.
