When the record type is not 00H, 01H, and 02H
When a checksum error occurs
Error between frequency measurement and baud rate
data. If the error is under 3%, the boot program decides on that frequency. Since
there is an overlap between the margin of 3% for 32.000 MHz and 33.868 MHz,
the boundary is set at the intermediate value between the two. The baud rate is
set based on the measured frequency. Each baud rate includes a set error shown in
Table 3.21.14. For example, in the case of 20.000 MHz and 9600 bps, the baud rate
is actually set at 9615.38 bps with an error of 0.2%. To establish communication,
the sum of the baud rate set error shown in Table 3.21.14 and frequency error
must be under 3%.
If the following errors occur in Intel Hex format when receiving the user
The boot program measures the resonator frequency when receiving matching
