S18F7: Write Data (host -> reading device, reply)

data. DATA- SEG defines the start address of the data to be written. DATALENGTH defines
the data volume of the
data to be written.

If both the DATASEG as well as the DATALENGTH are missing (elements with zero length), all
pages of the data area are overwritten. If only DATALENGTH is missing or if DATALENGTH
has the value zero, all data within the specified section must be written.
If the TARGETID is not known, a communication error (CE) occurs.
If DATASEG is missing (elements with zero length), the DATALENGTH value determines the
length of the data to be written. If the length of the data to be written is greater than the value
of the DATALENGTH, a communication error (CE) occurs.
S18F8: WRITE DATA ACKNOWLEDGE (WDA) (reading device ->host)
This message indicates whether the process for writing data on the antenna port specified in
the TARGETID was successful or failed.
