4.1 Using Terminal Count to Generate Interrupts
The MPA-100 allows the option of generating an interrupt whenever the Terminal Count
(TC) signal is asserted. Terminal Count is an indicator generated by the system’s DMA
controller, which signals that the number of transfers programed into the DMA controller’s
transfer register have occurred. This board feature only works when the interrupt sharing feature
is selected on jumper J4.
