• Max Records: The maximum number of records the log can hold given the record
size, and sector allocation. The data type is an unsigned integer from 0 - 2^32.
• Records Used: The number of records stored in the log. This number will equal the
Max Records when the log has filled. This value will be set to 1 when the log is
reset. The data type is an unsigned integer from 1 - 2^32.
NOTE:
The first record in every log before it has rolled over is a "dummy" record,
filled with all 0xFF's. When the log is filled and rolls over, this record is overwritten.
• Record Size: The number of bytes in this record, including the timestamp. The data
type is an unsigned integer in the range of 14 - 242.
• Log Availability: A flag indicating if the log is available for retrieval, or if it is in use
by another port.
