Note: If a memory cell does not operate normally and cannot be erased, one H'FF byte is
continuously at prescribed bit rate
host to indicate end of adjustment
of H'00 data transmitted by host
Host confirms normal reception
transmits one H'00 data byte to
indication (H'00), and transmits
After bit rate adjustment, chip
sets value in bit rate register
Chip calculates bit rate and
Chip measures low period
