Detailed Description

Payload structure for Direct CCC to one target.

Field Documentation

◆ addr

uint8_t i3c_ccc_target_payload::addr

Target address.

◆ data

uint8_t* i3c_ccc_target_payload::data
  • For Write CCC, pointer to the byte array of data to be sent, which may contain the Sub-Command Byte and additional data.
  • For Read CCC, pointer to the byte buffer for data to be read into.

◆ data_len

size_t i3c_ccc_target_payload::data_len

Length in bytes for data.

◆ num_xfer

size_t i3c_ccc_target_payload::num_xfer

Total number of bytes transferred.

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

◆ rnw

uint8_t i3c_ccc_target_payload::rnw

0 for Write, 1 for Read
