5. SIO STATUS READ
There is one status register to be read out by MICOM. There are 2 bit flags whigh are PE and WF respectivity.
The MICOM should check this status to test.
(1) Serial communication is successfully completed or not.
(2) Setting data are loaded into each register or not.
It is up to user to judge this flag or not.
