for a project I need to communicate with multidrop bus, a 9 bit UART communication. (no parity, one stopbit)

I tried to use the SerialPort class, but the SerialPort.DataBits property is out of range. It goes upto 8 databits.


In the AT915AM7X512 processors datasheet, I read that it can handle 9 bit USART communications through address bit handling.


Is it posssible with .NETMF to access or point to an absolute address and read or change the register data or control bit's?


I saw that the USART0 is in the 0xFFFC 0000 - 0xFFFC 3FFF range, I'm using C#.


anybody knows?
