7.4.6.4 SETAASA CCC

When the SETAASA CCC is issued by the host controller to the TMP139, it shall switch from I2C mode to I3C basic mode. The CCC takes effect after a Stop has been issued by the host controller. Once the SETAASA is received, the TMP139 shall set the MR18 register bit INF_SEL as 1'b1 for I3C basic mode of operation.

The CCC is always issues as a broadcast command, as shown in Figure 7-35, with no PEC bytes since it is applicable only during I2C mode.

Note:

TMP139 NACKs the SETAASA CCC if the previous CCC transaction has a parity error and the host starts the transaction with a Repeated Start.
