3. The application software should now examine the value of TWSR, to make sure that
4. When the address packet has been transmitted, the TWINT Flag in TWCR is set, and
5. The application software should now examine the value of TWSR, to make sure that
6. When the data packet has been transmitted, the TWINT Flag in TWCR is set, and
7. The application software should now examine the value of TWSR, to make sure that
the START condition was successfully transmitted. If TWSR indicates otherwise, the
application software might take some special action, like calling an error routine.
Assuming that the status code is as expected, the application must load SLA+W into
TWDR. Remember that TWDR is used both for address and data. After TWDR has
been loaded with the desired SLA+W, a specific value must be written to TWCR,
instructing the TWI hardware to transmit the SLA+W present in TWDR. Which value
to write is described later on. However, it is important that the TWINT bit is set in the
value written. Writing a one to TWINT clears the flag. The TWI will not start any oper-
ation as long as the TWINT bit in TWCR is set. Immediately after the application has
cleared TWINT, the TWI will initiate transmission of the address packet.
TWSR is updated with a status code indicating that the address packet has success-
fully been sent. The status code will also reflect whether a Slave acknowledged the
packet or not.
