TMS320F28388D: 关于CM核中的的I2C驱动,往寄存器写数据,寄存器数据还是0是为什么

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

有以下两个疑问:

1、使用如下程序发送数据

I2C_putMasterData(I2C0_BASE,0x55);
I2C_setMasterConfig(I2C0_BASE, I2C_MASTER_CMD_SINGLE_SEND);

向寄存器中写入数据,但寄存器中数据仍然是0

2、当debug时,或者reset时,没有向寄存器中写入数据,但是寄存器中已经有数据,如上图
