PCI-CTR05
9-111
Initial Duty Cycle - Enter a value between 0 and 1 to set the initial duty cycle.
The Duty Cycle defines the duty cycle at the initialization phase of the driver
similar to a initial value of an integrator.
Initial Toggle State - From the list, choose high or low. The Initial Toggle
State sets the initial digital level (high or low) of the output. For example, if
the Initial Duty Cycle is 0.25 and the Initial Toggle State is High, the first 25%
of the period will have a high level and the last 75% will have a low level.
Initial ARM State - From the list, choose Disarmed or Armed. The Initial
ARM State defines if the counter should be armed or disarmed after driver
initialization. The ARM State during a simulation can be controlled by the
second block input. If a value 0 is asserted, the counter is disarmed. If a value
1 is asserted, the counter gets armed.
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
-1
If two or more boards of this type are physically present in the target PC, enter
the PCI slot number of the board associated with this driver block.
PCI-CTR05 Counter FM
The PCI-CTR05 has one AM9513A chip with 5 counters.
The PCI-CTR05 FM driver programs the AM9513A for FM (Frequency
Modulation) signal generation (a square wave with fixed duty cycle and
variable frequency).
