2)
Write of 24 bit data
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.
(at the MIACK = “L”, waiting for becoming to MIACK = “L”)
The number of words of data written in while data required for the 16 bit address in a 24 bit
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.
It finished to write the data
Checking of MIACK = “L”
Write of 24 bit command
