The following sections detail the format and meaning of the configuration parameters from the Configuration
Parameters Memory Map, Table 2 .
The SequenceEventParameters field in the configuration parameters specifies the rail identification, monitoring
status, and sequencing options for each rail. The address map for these registers is as follows:
ADDRESS SIZE DEFAULT VALUE DESCRIPTION

0xE081 1 0x51 Rail 2 identification, monitoring status, and sequencing options
0xE082 1 0x52 Rail 3 identification, monitoring status, and sequencing options
0xE083 1 0x53 Rail 4 identification, monitoring status, and sequencing options
0xE084 1 0x54 Rail 5 identification, monitoring status, and sequencing options
0xE085 1 0x55 Rail 6 identification, monitoring status, and sequencing options
0xE086 1 0x56 Rail 7 identification, monitoring status, and sequencing options
0xE087 1 0x57 Rail 8 identification, monitoring status, and sequencing options
0xE088 1 0x00 GPO1 identification, sequencing options
0xE089 1 0x49 GPO2 identification, sequencing options
0xE08A 1 0x4A GPO3 identification, sequencing options
