1) Writing to this LSI (Transmission)
After “START Condition” is generated, 7-bit device address, R/
W(=0), command and argument are transmitted to this
LSI:.
2) Reading from this LSI (Data Request)
a.
After “START Condition” is generated, device address, R/ ̄
W(=0), command and argument are transmitted to
this LSI:.
b.
Generate “Repeated START Condition” and transmit device address and R/
W(=1) to this LSI.
c.
Data is continuously output from this LSI.
d.
This LSI Stops to output data when the master device returns NACK.
e.
Master device transmits “STOP Condition”.
After transmitting a command and argument to this LSI, “START Condition” can be generated again after generating
“STOP Condition”.
3) An example of implementation of built-in RAM Quick Read
Here shows an example of implementation of built-in RAM Quick Read.
After transmitting a command to this LSI, “START Condition” can be generated again after generating “STOP Condition”.
