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.
In addition, completion of internal taking in of write-in data requires the time of about 6 ms of the
maximum from END Condition.
Therefore, access of a next MCU needs to keep the term for about 6 ms after END Condition
transmission.
The procedure of the write of 24 bit data is shown in Figure 12.
Figure 12
Procedure of Write of 24 Bit Data
START Condition
Checking of ACK bit
= “L”
Write of 24 bit command
(write of data
= xxxx0xh)
Write of 24 bit data (n)
STOP Condition
It is data write-in completion after STOP Condition
transmission and within about 6 ms term.
A 16 bit address and a transmission word
number are set up.
It is possible to Write in the 24 bit data
until 16 word maximum.
At the time of ACK
= “H”, it resumes from
START Condition.
