BSCM Data
Event History
General
Description
The BSCM event history registers describe the last 10 encountered events. The BSCM events format
corresponds to a series of 10 records. Each record is composed of 5 registers describing one BSCM
event.
A block read request of 5x(n) registers is necessary to read the last n BSCM event records, where 5 is
the number of registers for each event record. The reading starts at the beginning of the block read (see
History Reading, p. 37).
For example, a block read request of 5x3 = 15 registers is necessary to read the last 3 BSCM event
records of the BSCM event history format:
z The first 5 registers describe the first BSCM event record (most recent event).
z The next 5 registers describe the second BSCM event record.
z The last 5 registers describe the third BSCM event record.
