Product data sheet
6.6.2 Read N bytes from I
6.6.3 I
6.6.4 Read buffer
Once the host issues this command, the SC18IS600/601 will start an I
transaction on the I
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
buffer”).
Note that the third byte sent by the host is the device slave address. The SC18IS600/601
will ignore the least significant bit so a read will always be performed even if the least
significant bit is a ‘0’. The maximum number of bytes to be read is 96.
Once the host issues this command, the SC18IS600/601 will start a write transaction on
the I
will read data from the specified 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.
