Is there anyway to put the USART into 9 bit data mode and then be able to set the 9th bit? We are trying to communicate with an external power supply over an RS-485 interface and the controller on the power supply uses a 9 bit data frame consisting of 8 bits of data with an additional framing bit. The first byte always has a 1 for the framing bit, all additional bytes have a 0.
I'm just not sure how to set this 9th bit on a per byte basis.
Anyone managed to do this with this device?
Thanks for your help
