1.2.22 TE0 Error Detection Does Not Take R/W Bit Into Consideration

An I3C Target should detect TE0 error by monitoring the bus for any of the following invalid combinations of Broadcast Address/W:

  • 7’h3E/W
  • 7’h5E/W
  • 7’h6E/W
  • 7’h76/W
  • 7’h7A/W
  • 7’h7C/W
  • 7’h7F/W
  • 7’h7E/R

With the exception of 7'h7E/R, the module flags a TE0 error immediately after the 7-bit address match happens, regardless of the status of the R/W bit.

Work around

None. However, the I3C Controller on the bus can send an HDR Exit Pattern for error recovery if the target device appears unresponsive on the bus.
