3.4 Start-up of the Modem Function
(b) For the buffer memory of the Q series C24
• The initialization data write (registration) and read operations are performed by designating an applicable
area that corresponds to registration numbers 8001H to 801FH for the user frame registration area
(addresses: 1B00H to 1FF6H). When deleting the initialization data, write "0" to the number of registration
data bytes designation area.
• The table below shows an overview of the buffer memory used in the write, read, and delete operations of
the initialization data as well as the designated values for each area. For more details, see Page 220,
CHAPTER 9. (Use the table by replacing the user frame with the initialization data.)
• The contents of the data to be written into the designated area that corresponds to registration numbers
8001H to 801FH are the same as those for the Flash ROM.
