Detailed Description

Payload structure for one CCC transaction.

Field Documentation

[struct]

struct { ... } i3c_ccc_payload::ccc

data

uint8_t* i3c_ccc_payload::data

Pointer to byte array of data for this CCC.

This is the bytes following the CCC command in CCC frame. Set to NULL if no associated data.

data_len

size_t i3c_ccc_payload::data_len

Length in bytes for optional data array.

err

enum i3c_sdr_controller_error_types i3c_ccc_payload::err

SDR Error Type.

Error from I3C Specification v1.1.1 section 5.1.10.2. It is expected for the driver to write to this.

id

uint8_t i3c_ccc_payload::id

The CCC ID (I3C_CCC_*).

num_targets

size_t i3c_ccc_payload::num_targets

Number of targets.

num_xfer

size_t i3c_ccc_payload::num_xfer

Total number of bytes transferred.

A Controller can abort a transfer before the length of the buffer. It is expected for the driver to write to this after the transfer.

payloads

struct i3c_ccc_target_payload* i3c_ccc_payload::payloads

Array of struct i3c_ccc_target_payload.

Each element describes the target and associated payloads for this CCC.

Use with Direct CCC.
