9.4.1 Registering user frames
The following shows an example of a sequence program when registering user frames in the Q series C24 flash ROM.
For details on the PUTE instruction, see Page 398, Section 17.7.
(When the Q series C24 I/O signals are X/Y80 to X/Y9F)
Data set for the program example are as follows:
● When registering a user frame in the flash ROM, to designate an user frame number that has already been registered,
delete the previously registered number and then reregister.
● The user should manage the number of total bytes for registered data.
● To check unregistered user frames, read the buffer memory (addresses: 205H to 21DH) indicated in Page 238, Section
9.4 (3).
● The SPBUSY instruction can be used to read the communication status by the dedicated instruction.
