O_TRG: Digital Output Trigger Signal

This bit is used to control the O_TRG output of PCI-7200, the signal is on CN1 pin 36 of PCI-7200 or CN1 pin 26 of cPCI-7200 when

1:O_TRG 1 goes High (1)

0:O_TRG 1 goes Low (0)

uDigital I/O FIFO Status:

I_OVR: Input data overrun

1:Digital Input FIFO is full (overrun) during input data transfer

0:No input data overrun occurred

Input data overrun occurred, the I_OVR bit is set when input FIFO is full and there is new input data coming in. This bit can be cleared by writing “1” to it.

O_UND: Output data FIFO is underrun

1:Output FIFO is empty during output data transfer

0:No output data underrun occurred

Output data underrun, the O_UND bit is set when output FIFO is empty and the output request for new data, this bit can be cleared by writing “1” to it.

uInterrupt Control:

In PCI-7200, the interrupt can be triggered by many signal sources such as O_ACK, I_REQ, timer 0, timer 1, and timer 2. The following bits control the interrupt source:

IO_ACK: Interrupt is triggered by O_ACK signal.

1:O_ACK interrupt is enabled

0:O_ACK interrupt is disabled

II_REQ: Interrupt is triggered by I_REQ signal.

1:I_REQ interrupt is enabled

0:I_REQ interrupt is disabled
