Transmits data H'AA to host when data
Echobacks the 2-byte data received.
Echobacks received data to host and also
transfers it to RAM (repeated for N times)
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.)
