I am using TL16CP754C in my project. With the hardware flow control enable, i am not able to stop the data transmission. I am making the CTS to high and low by connecting the CTS to VCC and GND. But without any respect to CTS, Data is transmitted to the receiver as soon as i switch on the system.
Please help me in this.
Have you enabled Auto-CTS#, bit 7 in the EFR register?
You have to write 0xBF to the Line Control Register in order to access the EFR register and set the Auto-CTS# bit - EFR
outportb(LCR_UART1, 0xBF); /* Enable EFR access */outportb(EFR_UART1, 0x80); /* Enable Auto-CTS# */outportb(LCR_UART1, 0x00); /* Disable EFR access */
