7.4.3 I2C Mode Operation

The I2C mode of operation is the primary mode of operation when the device is powered up, goes through a bus reset, or when a RSTDAA CCC is issued if the device is in I3C mode of operation. The maximum bus speed supported in this mode is up to 1.0 MHz. In this mode of operation, the following are not supported:

  1. IBI: If IBI is enabled during I3C basic mode, then switching to I2C mode shall disable the IBI enabling mechanism. If there are device events that cause the generation of IBI, then the status of the events shall be logged by the device in the respective register.
  2. Packet Error Check: This feature is not supported. If the host attempts to write data with a PEC byte, then the PEC byte shall be treated as a data byte and written to the register address in an incremental format.
  3. Parity Error Check: The parity error check is not supported except for the CCC that are listed in Table 7-6.

In the I2C mode of operation, the TMP139 supports SETHID, DEVCTRL and SETAASA CCC, and data transfer packets without PEC. Additionally, a Start or Repeated Start followed by 7'h7E with W = 0 is only allowed for the purpose of issuing the supported CCCs. Any other operation involving a Repeated Start shall be considered illegal.
