The first timestamp translates to an invalid date/time. (Note: This will not normally occur; this
procedure was created using a test module with some invalid data.)
Register Offset 7:6
= Last Hourmeter: 00 00 00 00
0.05 h/bit x 0 = 0.0 hours.
Register Offset 9:8
= First Hourmeter: 00 00 00 00
0.05 h/bit x 0 = 0.0 hours.
Register 10
= Flags/Count: F5 09
Since this register is defined bitwise, we first convert the hex value to binary.
$F5 09 = 1111 0101
0000 1001

The last bit is defined as bit 0.
Bits 11:8 Event Status = 0101
