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)
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
CIO-CTR10 Counter FM
The CIO-CTR10 has two AM9513A chip with 10 counters.
The CIO-CTR05 FM driver programs the AM9513A for FM (Frequency
Modulation) signal generation (a square wave with fixed duty cycle and
variable frequency).

Counter - From the list, choose 1, 2, 3, 4, or 5 to select which counter is used
with this driver block. In each case, one block is needed for each counter.
