Event Commands

Notes:
  1. 1.This is a hard-coded read-only bit. This Target module does not support secondary Controller features, so the CREN bit will always read ‘0’.
  2. 2.The value of this read-only register is determined by the Controller after issuing an ENEC or DISEC CCC.
  3. 3.This register follows the definition of ENEC/DISEC Command Byte format as per the MIPI I3C Basic 1.0 Specification.
