Trying to understand the MODIR values/settings for hardware handshaking
I have a simple setup, two SK146 EVBs sitting next to each other.
Connections are crossed, Rx to Tx and CTS to RTS.
Both boards have UART 0 configured in the same way, one od sending a short message out periodically.
For the purpose of this design, interrupts cannot be used and the receiver is polling the status register and so flow control is required.
There are 8 bits of MODIR involved in the configuration of the handshaking but I find the explanation very confusing.
Is there an application note for this?
Or can someone simply share a known working value for basic cross-connected handshaking?
