5.8.4 LAST n ERROR EVENTS Page (07h)

This page returns one parameter at a time that contains the ASCII text for the specified event
log. The Parameter Number field in the CDB specifies the log event to return. The log events
in EEPROM are numbered from 0 to 255, after which the number wraps back to 0; only a
limited number of events are stored at a given time (up to 48). The log event that is returned
is the one whose Parameter Code is equal to, or the first one greater than, the Parameter
Number specified in the command control block.
