SC18IS600/601
SPI to I2C-bus interface
6.6.2 Read N bytes from I2C-bus slave device
Once the host issues this command, the SC18IS600/601 will start an I2C-bus read
transaction on the I2C-bus to the specied slave address. Once the data is received, the
SC18IS600/601 will place this data in the receiver buffer, and will generate an interrupt on
the INT pin. The ‘transaction completed’ status can be read in the I2CStat. Note that the
data is not returned until a Read Buffer command is performed (see Section 6.6.4 “Read
Note that the third byte sent by the host is the device slave address. The SC18IS600/601
will ignore the least signicant bit so a read will always be performed even if the least
signicant bit is a ‘0’. The maximum number of bytes to be read is 96.
6.6.3 I2C-bus read after write
Once the host issues this command, the SC18IS600/601 will start a write transaction on
the I2C-bus to the specied slave address. Once the data is written, the SC18IS600/601
will read data from the specied slave, place the data in the Receiver Buffer and generate
an interrupt on the INT pin. The ‘transaction completed’ status can be read in I2CStat.
Note that the data is not returned until a ‘Read Buffer’ command is performed.
