CIO-CTR05
9-7
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-CTR05 counter PWM & ARM
The CIO-CTR05 has one AM9513A chip with 5 counters.
The CIO-CTR05 PWM & ARM driver programs the AM9513A for PWM or
disarmed signal generation (a square wave with fixed frequency and variable
duty cycle). Additionally the driver allows to arm and disarm the counter by the
second block input.

Driver Block Parameters
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.
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-CTR05 has to be in
position 1MHz not 5MHz.
Relative Output Frequency - Enter a value less than 1. The Relative
Output Frequency is multiplied by the FrequencyBase to set the fixed
output frequency of the PWM-signal.
For example, if the output frequency of a square wave has to be 17.5 kHz, then
choose F2=100kHz as the Frequency Base and enter
0.175 as the Relative
Output Frequency. 100kHz x 0.175 = 17.5 kHz
