Figure 7–11. Slave Address Bits
After the master sends a start condition and the slave address byte, the ALTUFM_I2C
logic monitors the bus and responds with an acknowledge (on the SDA line) when its
address matches the transmitted slave address. The ALTUFM_I2C megafunction then
performs a read or write operation to or from the UFM, depending on the state of the
bit.
Byte Write Operation
The master initiates a transfer by generating a start condition, then sending the correct
slave address (with the R/W bit set to 0) to the slave. If the slave address matches, the
ALTUFM_I2C slave acknowledges on the ninth clock pulse. The master then transfers
an 8-bit byte address to the UFM, which acknowledges the reception of the address.
The master transfers the 8-bit data to be written to the UFM. After the ALTUFM_I2C
logic acknowledges the reception of the 8-bit data, the master generates a stop
condition. The internal write from the MAX V logic array to the UFM begins only
after the master generates a stop condition. While the UFM internal write cycle is in
progress, the ALTUFM_I2C logic ignores any attempt made by the master to initiate a
new transfer.
