Limit Checking Input Signals
The Valid Band for Limit-Checking an analog input signal, has a freely programmable position and
size within the entire result range. The settings should be mapped in two boundary registers(0/1).
Out-of-Range will set a BFL, if the corresponding activation / enable flags (BFLA / BFLE) are set.

CCU Trap on Out-of-Range Detection (BFL) – Requires ERU
If activated (by the BFLA), the Boundary Flag (BFL) may issue a CCU Trap, if enabled.
