部件号：AM5716 大家好，
客户在AM5716 IC2主地址发送从属地址期间观察到奇怪的行为。 I2C5主控制器无法 使总线繁忙以进行传输，并按如下所示的ACK位定时发送数据。 发生了1次/ 2到3小时。
I2C5与外部RTC通信。 I2C5模块停留在Line15，该总线正忙于 连接的代码。
您对此问题有什么想法吗？
/* Set i2c slave address */
I2CMasterSlaveAddrSet( baseAddress, slaveAddress );
I2CFIFOClear(baseAddress, I2C_TX_MODE);
I2CFIFOClear(baseAddress, I2C_RX_MODE);
/*Clear all interrupt status*/
I2CMasterIntClearEx(baseAddress, I2C_INT_ALL);
/* Set data count */
I2CSetDataCount( baseAddress, size+1 );
/* Configure i2c as master-transmitter and to generate stop condition */
I2CMasterControl(baseAddress, I2C_CFG_MST_TX);
/* generate start */
I2CMasterStart(baseAddress);
/* wait for bus busy */
while(I2CMasterBusBusy(hwAttrs->baseAddr)==0)
{
}
// data TX
for (i = 0; i < (size+1); i++){
/*Wait for transmit interrupt to occur*/
while (I2CMasterIntRawStatusEx(baseAddress,
I2C_INT_TRANSMIT_READY) != I2C_INT_TRANSMIT_READY) {
｝
/* Send the data */
I2CMasterDataPut(baseAddress, txBuf[i] );
/*Disable transmit ready and stop condition interrupt*/
I2CMasterIntClearEx(baseAddress, I2C_INT_TRANSMIT_READY);
}
/* generate stop when requested */
I2CMasterStop(baseAddress);
/*Clear data buffer length*/
I2CSetDataCount(baseAddress, 0);
谢谢，此致，
