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
After bit rate adjustment, SH7051
of H'00 data transmitted by host
transmits one H'00 data byte to
Host confirms normal reception
indication (H'00), and transmits
SH7051 calculates bit rate and
SH7051 measures low period
sets value in bit rate register
SH7051 transmits one H'AA
of bit rate adjustment end
Host transfers data (H'00)
and execute reset-start
Set pins to boot mode
transmitted as an erase error, and the erase operation and subsequent operations
are halted.
After receiving H'55,
one H'55 data byte
data byte to host

Figure 19.4 Boot Mode Execution Procedure
Host transmits programming control

program sequentially in byte units
SH7051 transmits one H'AA data
