RS-232/422/485 Enable TX Interrupt block
Simulink® Real-Time™ Library for RS-232
The Enable TX Interrupt block enables the transmitter buffer empty interrupt when data is present in the software FIFO.
The input port for controlling the interrupt is a Boolean value. If the input port value is true, the Enable Transmit Interrupt block enables the transmitter buffer empty interrupt in the UART. After the interrupt service routine empties the software FIFO, the interrupt is disabled.
The Commtech/Fastcom and Quatech® 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/products.
Enter the base address of the UART for which you want to enable the transmitter buffer empty interrupt.
From the list, choose a port. This parameter specifies the input port for which this block enables the interrupt.
If only one board of this type is in the target computer, enter
automatically locate the board.
If two or more boards of this type are in the target computer,
enter the bus number and the PCI slot number of the board associated
with this driver block. Use the format
To determine the bus number and the PCI slot number, type:
tg = slrt; getPCIInfo(tg, 'installed')
