Writes Addressing as I2C Master
[ Procedure 2 ]
Addressing read procedure
From the write mode, S1S60000 writes the address to be read and then turns on the read mode to read the actual
data.
(1) S1S60000 sends the start condition
(2) S1S60000 sends the slave address of the external device and R/W bits from the write mode
(3) Confirms acknowledge from the external device
(4) S1S60000 sends the address to be written to the external device
(5) Confirms acknowledge from the external device
(6) S1S60000 sends the start condition (stop condition is not sent): Restart
(7) S1S60000 sends the slave address of the external device and R/W bits from the read mode
(8) Confirms acknowledge from the external device (from this step, S1S60000 becomes the receiver and the
external device becomes the transmitter)
(9) The external device sends data of the address specified in (4) above
(10) S1S60000 sends acknowledge to the external device
(11) As needed, (9) and (10) are repeated. Addresses to be read are automatically incremented in the external
device.
(12) S1S60000 sends “1” as acknowledge
(13) S1S60000 sends the stop condition
In the above steps, the restart in (6) is automatically generated if the upper bits for containing the transmit data
are specified.
And, acknowledge in (12) is automatically output as S1S60000 received every specified data.
