data : 1 byte of memory card data.
Description :
This command allows writing single bytes of data to the memory
card. This is useful for writing small chunks of data relating to graphics objects
or user application specific data for general purpose storage. For large data
blocks it is more efficient to use the Write Sector Data command described in
the previous section.
Before this command can be used the card memory address location must be
set using the Set Memory Address command. Once this command is sent, the
µOLED
will write 1 byte of data relating to that memory location set by the
memory Address pointer. The memory Address location pointer is automatically
incremented to the next address location.
Only the data byte is stored in the card. Other bytes in the command message
are not stored.
