TC9446FG
2) Write of 24 bit data
The number of words of data written in while data required for the 16 bit address in a 24 bit
command is set up and R/W bit is set to “L”, when writing in data from a MCU to TC9446FG during
program operation is set up.
And, 24 bit data of the number required after transmitting a 24 bit command of words is written in.
The procedure of the write of 24 bit data is shown in Figure 3.
MICS = “L”
Checking of MIACK = “L”
(at the MIACK = “L”, waiting for becoming to MIACK = “L”)
Write of 24 bit command
(write of data = xxxx0xh)
Setting of 16 bit address and umber of the
transmission word.
Write of 24 bit data (1)
Write of 24 bit data (2)
It is possible to write the 24 bit data until
16 word maximum.
Write of 24 bit data (n)
MICS = “H”
It finished to write the data
