suring or counter
function
The command register for the multi-purpose input MFQEx is bit-coded. By setting
several bits, you can issue several commands simultaneously.
You can activate frequency or period measuring or the counting function for multi-
purpose input MFQEx as follows:
1.
Activate the input:
To this end, enter value 0 into R 6010x0001.
2.
If you want to measure a frequency with gate time, then write a value not
equal to zero as gate time into R 6010x0005. Enable frequency measuring by
entering value 0x0040 into R 6010x0001.
If you want to count increments, enter 0x0030 into R 601x0001.
If you want to measure a period time, enter 0x0040 into R 601x0001.
ð
The result is contained in R 6010x0003.
7.7 Multi-purpose outputs
Introduction
The table below lists the functions of the multi-purpose outputs:
■
Current measurement
■
Digital output, adjustable as high-side or low-side output
■
Output of PWM signals
■
Operation as H-bridge

Example
x = 5 for multi-purpose output PA3. To activate the digital output of PA3 enter
command 0x0008 into R 601050001.
Registers - Over-
