Data indicating number of received
words is read from address 251 of the
shared memory (received buffer of
CH1).
Block check code is calculated.
− Number of bytes received is calcu-
lated (not including BCC).
− Block check code is calculated.
− Result is converted from HEX to
hexadecimal ASCII code.
BCC segment is extracted from re-
ceived data.
Number of received data bytes is
judged to be even or odd.
R100
Number of received data bytes is
odd.
If odd, data is shifted one byte to
the right.
BCC is judged as OK or NG.
