Data Fields
bool	single_byte_start_cond_delayed
	If true, generation of the start condition in single-byte mode is delayed until the address is transmitted.

bool	single_byte_address_delayed
	If true, transmission of the address in single-byte mode is delayed until the first data byte is read/written.

bool	supports_single_byte
	If true, the single-byte API is implemented. Otherwise, it is a no-op.

bool	supports_zero_length_transfer_single_byte
	If true, the single-byte API supports a zero-length transfer (one that has only a start, then an address, then a stop).

bool	supports_zero_length_transfer_transaction
	If true, the transaction-based API supports a zero-length transfer (one that has only a start, then an address, then a stop).

◆ single_byte_start_cond_delayed

bool single_byte_start_cond_delayed

If true, generation of the start condition in single-byte mode is delayed until the address is transmitted.

If single-byte is not supported this is a don't care.

Definition at line 114 of file i2c_api.h.

◆ single_byte_address_delayed

bool single_byte_address_delayed

If true, transmission of the address in single-byte mode is delayed until the first data byte is read/written.

For write transactions, the ACK/NACK from the address byte will be reported in the status of the first data byte. Note that this means there is no way to detect a NACK of the address for a single-byte read operation. If single-byte is not supported this is a don't care.

◆ supports_single_byte

bool supports_single_byte

If true, the single-byte API is implemented. Otherwise, it is a no-op.

◆ supports_zero_length_transfer_single_byte

bool supports_zero_length_transfer_single_byte

If true, the single-byte API supports a zero-length transfer (one that has only a start, then an address, then a stop).

If single-byte is not supported this is a don't care.
