Hi Cresil,
I am facing the same issue.
For first bye (address byte), 9th bit is MARK.
and other data it is SPACE.
Using this combination.
9th bit UART_LCR[5] UART_LCR[4] UART_LCR[3]
===== ============ ============ ============
(Forced 1) 1 0 1
(Forced 0) 1 1 1
But it is observed on scope that 9th bit remains '0' for all data.
Will yopu please assist me to solve this problem.
Thanks in Advance.
Regards,
Ankit
