Note: The setting for the size of the initial programming program must be in the range from H'0001to H'2000. If the size is set to H'0000 or
n = n + 1
greater than H'2001, normal operation is not possible.
Figure 17.3 Procedure for Execution of Boot Processing
No
Transmit 10 continuous bytes of H'00
data at prescribed bit rate
Execute initial programming program
Transmit initial programming program
as a sequence of bytes
Transmit two bytes to indicate size
of initial programming program
(number of bytes: N); upper byte
followed by lower byte
Confirm successful reception of
notification of end of bit-rate
adjustment (H'00), and transmit one
byte of data (H'55)
After receiving data (H'AA),
go to next step
Receive echo-back data (n = 1)
After receiving data (H'AA),
go to next step
and received data match?
and received data match?
Receive echo-back data

Transmit received program to external
host as verified data (echo-back)
Transmission/Reception are disabled
Set BOOT_E pin to boot mode and
execute start-up from a power-on reset
Transmit received number of bytes (N)
to external host as verified data
(echo-back)
Measure low period in data (H'00)
being transmitted by external host
Calculate bit rate and set value in
bit-rate register (SCBRR)
After bit-rate adjustment, transmit
one byte of data (H'00) to notify
external host of completion of
adjustment
After receiving data (H'55), transmit
one byte of data (H'AA) to external
host
Branch to initial programming program
Transmit one byte of data (H'AA)
Transfer received program to
on-chip RAM (U memory)
(SCSCR 0 = H'00)
