RS-232/422/485 Filter Interrupt Reason block
Simulink® Real-Time™ Library for RS-232
The Filter Interrupt Reason block filters the output of the Read Int(errupt) Status block.
Note: The Diamond Systems PC/104 boards and blocks will be removed in a future release. Do not use them in new models. Instead, use boards and blocks available from www.speedgoat.com.
If the condition that the interrupt query block reads from the IIR register matches the one chosen here, the output is true.
This block is used exclusively inside the interrupt service subsystem for this board.
From the list, choose a port. This parameter specifies the port from which this block gets control data.
From the list, choose
Modem status change. This parameter
specifies the interrupt reason that this filter block is looking for.
Modem status change currently does
nothing because the interrupt is not enabled.
