TMS320C5505 flow control pin behavior when UART autoflow disabled

AM44866

Hello,

What state is the RTS pin in when UART autoflow is disabled on the C5505 (output driving hi, driving low, or high-z)? Also, does the CTS pin remain an input?

Thanks - AM

AM,

It took some time to dig in design files. RTS will be always driven and CTS will be always input regardless of autoflow control.

Hi Peter,

Thanks for the response, would you happen to know what level the RTS signal will be driven to in this situation (hi, low)?

Hi,

I would think it'll be a state of the previously set. I did some experiment but I could not get the signal out. It was always stayed low.

Regards,

Hyun
