Organization blocks If you want to use a shift register, there are three special function
organization blocks available:
•• OB 240:
This funciton
initializes a shift register.
•• OB 241:
This function
processes a shift register.
•• OB 242:
This function
deletes a shift register.
Continuation of the example:
You can now evaluate the information in the pointers as follows:
:L FY 0
:
etc.
Flag bits 0, 3 and 2 can be scanned at the base pointer: in this way,
you can evaluate all the information from the entries in all pointers at
the base pointer (in the example, this requires twelve clock pulses).
