| #define MTB_LIN_IOCTL_READ_STATUS (0x00U) |
Optional status indicators.
The first bit in this byte is the flag that indicates there was no signalling on the bus for a certain elapsed time (available when the Bus Inactivity Timeout Detection option is enabled). If the elapsed time passes a certain threshold, this flag is set.
The second bit is the flag that indicates that a Targeted Reset service request (0xB5) is received (when J2602-1 Compliance is enabled).
Calling this API clears all the status bits after they are returned.
Parameters: The pointer to l_u16, where the status will be written.
| #define MTB_LIN_IOCTL_SET_BAUD_RATE (0x01U) |
Set a baud rate.
Parameters: l_u16*.
| #define MTB_LIN_IOCTL_SLEEP (0x02U) |
Prepare the device for the Low-power mode entry.
Parameters: None.
| #define MTB_LIN_IOCTL_WAKEUP (0x03U) |
Restore the LIN middleware state after a wakeup.
Parameters: None.
| #define MTB_LIN_IOCTL_SYNC_COUNTS (0x04U) |
Return the current number of the sync field timer counts in "pv".
Parameters: The pointer to l_u8, where the number will be written.
| #define MTB_LIN_IOCTL_SET_SERIAL_NUMBER (0x05U) |
Update the pointer to the serial number.
Parameters: The pointer to l_u8, where the serial number will be written.
| #define MTB_LIN_IOCTL_GET_NAD (0x06U) |
Return the configured NAD.
Parameters: The pointer to l_u8, where the NAD will be written.
| #define MTB_LIN_IOCTL_SET_NAD (0x07U) |
Set the configured NAD to any value except 00, 7E or 7F.
In J2602 compliance mode, frame PIDs are also updated according to the new NAD.
Parameters: The pointer to l_u8, where the NAD will be read from.
| #define MTB_LIN_IOCTL_GET_FRAME_PID (0x08U) |
Returns the frame PID by the frame table index.
Reports an error if the frame PIDs cannot be updated due to the NAD and frame count mismatch (see SEA J2602-1 specification 5.7.2.2 Message ID Assignment, Table 1).
The NAD is not updated if a message PID update fails.
Parameters: The pointer to mtb_stc_lin_new_pid_by_msg_t, where the NAD will be written.
| #define MTB_LIN_IOCTL_SET_FRAME_PID (0x09U) |
Sets the frame PID by the frame table index.
Parameters: The pointer to mtb_stc_lin_new_pid_by_msg_t, where the NAD will be read from.
