7.4.6.1 ENEC CCC
The ENEC CCC is issued by the host controller to enable the event interrupt generation. The CCC takes effect
after a Stop has been issued by the host controller. Once the ENEC is received, the TMP139 shall update the
MR27 register bit IBI_ERROR_EN to 1'b1.
Note
It is illegal for the host controller to send the ENINT bit as 0.
The command may be issued either as a broadcast command or as a direct command to TMP139 as shown in
Figure 7-25 and Figure 7-26.
