SC16C554IB80 echo issue

[khg]

Hi,

I use SC16C554IB80 for our product. I set register as it follows:

Write_SC16( SC16_REG_MCR, 0x08, ch);
Write_SC16( SC16_REG_IER, 0x07, ch);
Write_SC16( SC16_REG_FCR, 0x07, ch);
Write_SC16( SC16_REG_FCR, 0x01, ch);

and incoming data is processed it follows:

while(Read_SC16(SC16_REG_LSR, 0)&0x01) // check received data of port a
{
unsigned char temp = Read_SC16(SC16_REG_RHR, 0);

...

}

And then there is TX echo.

I want to get rid of TX echo but I can't.

Hello,

Could you answer me the next questions, please?

Is that all the configuration you do to the device?

Also, after you read, do you perform any other action?

Thank you!

Best regards,

Aldo.
