4-5-1 Data receiving procedure
In case of receive error
Communication ready
Receive data (R_DAT)
Receive data length (R_LEN)
Receive status (R_STS)
Receive end (R_END)
Receive error (E_ERR)
R_END
Continuous receiving operation
While the communication ready flag is turned ON, whether the data to be received exists or not is checked continuously
and, when it exists, the operation for receiving is executed. When a delimiter between data frames is detected, the
received data and the number of receive data bytes are stored in R_DAT (receive data) and R_LEN (receive data length),
respectively, and the R_END (receive end) flag is turned ON (for only one pulse). The result of receiving is stored in
R_STS (receive status). If a receive error has occurred, R_END (receive end) and E_ERR (receive error) are turned ON
(for only one pulse).
