· Measures low-level period of receive data H'00.
· Calculates bit rate and sets it in BRR of SCI3.
· Transmits data H'00 to the host to indicate that the
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.)
Echobacks the 2-byte received data to host.
