Enumerations

enum  i3c_addr_slot_status {
  I3C_ADDR_SLOT_STATUS_FREE = 0U , I3C_ADDR_SLOT_STATUS_RSVD , I3C_ADDR_SLOT_STATUS_I3C_DEV , I3C_ADDR_SLOT_STATUS_I2C_DEV ,
  I3C_ADDR_SLOT_STATUS_MASK = 0x03U
}
 Enum to indicate whether an address is reserved, has I2C/I3C device attached, or no device attached. More...
