+  This block allows to read the digital inputs on the RPP board. For pins number 0-7 is not

+  can be in model. And oppositely for other pins (8-15) are not relevant and visible parameters
+  of names 'Pull' and 'Active'. The variable threshold check change the read mode of the pin. For 
+  setting it see Digital Input Configure block.
