Sample Circuit for Changing Slave Address
Figure 8.4 Sample Circuit for Changing Slave Address
TIP
- Although the above circuit can be used to change or set slave addresses, we recommend using an
addressing device instead for improved ease of use and maintainability.
- The above sample circuit changes the slave address from 1B($21) to 6B($26). For details, see the
table below.
- The above circuit cannot be used to change a slave address suffix from A slave to B slave and vice
versa. To do so, use an addressing device instead.
- After performing forced set on AdrSet, the program resets AdrsSet2 if the slave address update is
successful. You can refer to the LDS to check the slave address before and after the update.
- See also Section 7.2.
