This block programs the AMD9513A for capturing FM signals.
There is one output for relative frequency compared to the base frequency. To get the actual frequency, multiply the base frequency by the relative frequency.
The FM signal has to enter the pin named GATE of the corresponding counter channel. The CLK pin has to be left unconnected.

Driver Block Parameters
Counter -- From the list, choose 1, 2, 3, 4 or 5. This selects which counter the driver block uses to determine the FM. In each case, one block is needed for each counter.
Frequency base -- From the list, choose F1=1MHz, F2=100kHz, F3=10kHz, F4=1kHz, or F5=100Hz to set the base frequency. The XTAL frequency is assumed to be 1MHz, therefore the jumper on the PCI-CTR05 has to be in position 1MHz not 5MHz.
Sample time -- Enter the base sample time or a multiple of the base sample time. The sample time indicates the update rate of registration on the input (Duty Cycle)
PCI Slot (-1:autosearch) -- Enter a number between -1 and n. If only one board of this type is physically present in the target PC, enter
If two or more boards of this type are physically present in the target PC, enter the bus number and the PCI slot number of the board associated with this driver block. Use the format [BusNumber, SlotNumber]. To determine the bus number and the PCI slot number, type
