Clearing Receiver Line Status Interrupt
Information:
Type :: BUG
Status :: CLOSED
Assigned to ::
Howard, A. LeFevre
Description:
When using the Receiver Line Status Interrupt (IER(2) = 1) I observe the following behaviour:
* A character with parity, framing or break error was received and the LS interrupt is set.
* When now the LSR is read, the LS interrupt is not cleared how it is described in the IIR.
* But when the top character from the Rx FIFO is read then the LS interrupt is cleared immediately.
What I expect is that the LS interrupt can be cleared by reading the LSR any time, independently of the top charater in the Rx FIFO.
