The µ-Processor may obtain the following data about the FIFO-buffers status:
•
•
•
•
The SL RC400 can generate an interrupt signal
•
•
The flag HiAlert is set to 1 if only WaterLevel bytes or less can be stored in the FIFO-buffer. It is generated
by the following equation:
The flag LoAlert is set to 1 if WaterLevel bytes or less are actually stored in the FIFO-buffer. It is generated
by the following equation:
Number of bytes already stored in the FIFO-buffer: FIFOLength
Warning, that the FIFO-buffer is quite full: HiAlert
Warning, that the FIFO-buffer is quite empty: LoAlert
Indication, that bytes were written to the FIFO-buffer although it was already full: FIFOOvfl
FIFOOvfl can be cleared only by setting bit FlushFIFO.
If LoAlertIRq is set to 1 it will activate Pin IRQ when LoAlert changes to 1.
If HiAlertIRq is set to 1 it will activate Pin IRQ when HiAlert changes to 1.
