CIO-CTR10 FM Capture
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.

Driver Block Parameters
Counter - From the list, choose 1, 2, 3, 4 or 5, 6, 7, 8, 9, or 10. 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 CIO-CTR10 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)
BaseAddress - Enter the base address of the board. This entry must
corresponds to the DIP-switch settings on the board. For example, if the base
address is 300 (hexadecimal), enter
0x300
