automatically restored to the beginning of the log file so that the next read request will return the first (oldest)
event. To point to an arbitrary record, use the log partition status/control registers A100h-A107h (see Section
5.13).

Parameter Offset Type R/W Range
Status indication +0 UINT16 R Bit-mapped register:
bit 0 = 1 - the end record is being read (the end of a
log file reached)
bit 1 = 1 - reading after the end of file: the read
pointer has rolled over the end of a log file, i.e., the file
is being re-read from the beginning. This bit is cleared
when a new record is being read, or the read
sequence has changed by overwriting the partition
pointer.
bit 8 = 1 - no records logged in the partition
bit 9 = 1 - the record is corrupted
bit 15 = 1 - read error (detailed by bits 8-9)
The record sequence number +1 UINT16 R 0 to 65535 (increments modulo 65536 with each log)

Timestamp is given in local time in a UNIX-style time format: it represents the number of seconds since midnight
(00:00:00), January 1, 1970. The time is valid after January 1, 2000.

For the log value size and range, refer to Table 5-7.
NOTES:
1. If a requested record is corrupted (the redundant check fails), the record is reported with all zeros (except the sequence
number) and the bits 9 and 15 in the status indication word being set to 1.
2. If a record is requested when the log file is empty, the record is reported with all zeros and bits 8 and 15 in the status
indication word being set to 1.
