• Measures low-level period of receive data H'00.
• Calculates bit rate and sets BRR in SCI_1.
• Transmits data H'00 to host as adjustment end
Transmits data H'AA to host when data H'55 is
received.
Checks flash memory data, erases all flash
memory blocks in case of written data
existing, and transmits data H'AA to host.
(If erase could not be done, transmits data
H'FF to host and aborts operation.)
