1. Function description

	1. I2S master mode sends data by interrupt

2. Use environment

	/* Software development environment: the name and version number of the software tool used in the current project */
	IDE tool: KEIL MDK-ARM 5.30.0.0
	SDK version: Nsing.N32G030_Library.1.1.1

	/* Hardware environment: the development hardware platform corresponding to the project */
	Development board: N32G030CL-STB V1.0 V1.1

3. Instructions for use

	/* Describe related module configuration methods; for example: clock, I/O, etc. */
	1. SystemClock: 48MHz
	2. GPIO: (main mode DEMO board) I2S1: WS--PA4, CK--PA5, SD--PA7
	Slave mode DEMO board) I2S1: WS--PA4, CK--PA5, SD--PA7
	3. Interrupt: I2S1 interrupt entry function SPI1_IRQHandler

	/* Describe the test steps and phenomena of the Demo */
	1. After compiling, download the program to reset and run;
	2. Enter the debug mode on the slave mode DEMO board, first press and hold the reset button of the master mode DEMO board,
	   and then run the slave mode DEMO board at full speed,Release the DEMO board reset button in the main mode again.

4. Matters needing attention
	Two demo boards are required, one board to program the master mode program, one board to program the slave mode program, 
	the two boards need to be powered on together, and connect the VCC and GND of the two boards
