Writing 24-bit data
When the host microcontroller writes data to the TC94A48FG during the execution of a program, it
sets a 16-bit address in a 24-bit command as well as sets its R/W bit to "0" and sets the number of
words to be written. Then, it transfers the 24-bit command, followed by a required number of 24-bit
data words.
Figure 7 shows the 24 bit data write procedure.
