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
