&par Example Description

This example shows how to configure LPI2C peripherals to communicate between two different boards
in interrupt mode. Run Slave board first, after that Run Master board.

First, Master sends data to the slave, and then wait the ACK of the slave.
Then Master receive data from the slave to the master buffer.
If the transfer is successful, Green LED will turn on, otherwise red LED will turn.
You can view the transmission information through the UART.

KEY1:        PC12

LPUART1 is configured as follows:
    - TX:PC7, RX:PC6
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Transmit enabled
