37.4.21 I3CxFEAT

Note:
  1. This is a hard-coded read-only bit. This Target module does not support HDR mode, so the HDRCAP bit will always read ‘0’.
  2. Once a Hot-Join Request has been initiated, the device responds to all forthcoming ENTDAA CCCs, even when the Dynamic Address is cleared using RSTDAA CCC. Refer to Hot-Join Mechanism for more information.
  3. To guarantee expected behavior, this register should only be written when the module is disabled (EN = 0).
