write Byte Data to Memory Card

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.
