Overview
========
The example shows how to use i3c driver as slave to do board to board transfer with a polling master.

In this example, one i3c instance as slave and another i3c instance on the other board as master. Master
first sends a piece of data to slave in I2C mode, and receive a piece of data from slave and check if the
data received from slave is correct. Then master will enter dynamic address cycle to assign address to the
connected slave, after success, will use I3C SDR mode to transfer data, then receive data from the connected
I3C slave and check the data consistency.

Toolchain supported
===================
- IAR embedded Workbench  9.40.1
- Keil MDK  5.38.1
- GCC ARM Embedded  12.2
- MCUXpresso  11.8.0

Hardware requirements
=====================
- Micro USB cable
- LPCXpresso55S36 board
- Personal Computer

Board settings
==============
I3C one board:
  + Transfer data from MASTER_BOARD to SLAVE_BOARD of I3C interface, I3C0 pins of MASTER_BOARD are connected with
    I3C0 pins of SLAVE_BOARD
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
MASTER_BOARD        CONNECTS TO         SLAVE_BOARD
Pin Name   Board Location     Pin Name   Board Location
P0_9       J9-20              P0_9       J9-20
P0_24      J9-18              P0_24      J9-18
GND        J9-14              GND        J9-14
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Connect the jumper resistor R554 2-3.

Prepare the Demo
================
1.  Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J1) on the board
2.  Open a serial terminal with the following settings:
    - 115200 baud rate
    - 8 data bits
    - No parity
    - One stop bit
    - No flow control
3.  Download the program to the target board.
4.  Press reset button to begin running the demo.

Running the demo
================
The following message shows in the terminal if the example runs successfully.
