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.
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.
The command may be issued either as a broadcast or as a direct command, as shown in Figure 7-27 and Figure 7-28, with PEC Enabled. In such a case the host controller shall append the PEC byte calculated on all bytes except the byte with 7'h7E and R/W=0 after the Start or Repeated Start.
TMP139 NACKs the ENEC CCC if the previous transaction has a parity or PEC error and the host starts the transaction with a Repeated Start.
