Part Number: TMS570LS3137
Hi Team,
Using the following code to read the data on the AT32C256 EEPROM, it was found that there was an extra stop signal before the second start signal, but the data seemed to be read out without problems. How can I not let this stop signal generate?
uint8_t RX_Data_Master[10]={0xaa,0xbb};
/* wait until MST bit gets cleared, this takes
* few cycles after Bus Busy is cleared */
// while(i2cIsMasterReady(i2cREG1) != true);
/* Configure address of Slave to talk to */
i2cSetSlaveAdd(i2cREG1, SLA_ADDR);
/* Set direction to Transmitter */
/* Note: Optional - It is done in Init */
i2cSetDirection(i2cREG1, I2C_TRANSMITTER);
/* Configure Data count */
/* Slave address + Word address write operation before reading */
i2cSetCount(i2cREG1, 2);
/* Set mode as Master */
i2cSetMode(i2cREG1, I2C_MASTER);
/* Set Stop after programmed Count */
i2cSetStop(i2cREG1);
/* Transmit Start Condition */
i2cSetStart(i2cREG1);
/* Send the Word Address */
i2cSendByte(i2cREG1, 0x00);
i2cSendByte(i2cREG1, 0x10);
/* Wait until Bus Busy is cleared */
while(i2cIsBusBusy(i2cREG1) == true);
/* Wait until Stop is detected */
while(i2cIsStopDetected(i2cREG1) == 0);
/* Clear the Stop condition */
i2cClearSCD(i2cREG1);
