6.4.1 Outline of System Registers
The LED indicators on the front of the MP2100/MP2100M can be used to determine MP2100/MP2100M operat-
ing status and error status. To obtain more detailed information on errors, the system registers (S registers) can be
used. A detailed check of the contents of system registers can be used to determine the location of the error and
take the corrective measures.
