Transmits data H'AA to host.
Echobacks the 2-byte data
received to host.
Echobacks received data to host and also
transfers it to RAM.
(repeated for N times)
• Measures low-level period of receive data
• Calculates bit rate and sets BRR in SCI3.
• Transmits data H'00 to host as adjustment
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.)
