Execution result storage area
Operand Items Description
[D1]
Execution result
code
(Note 1)
Stores the execution result code.
HFFFF: Executing
H0: Normal end
H1: Dual-boot error
H2: SD memory card cover open error

Acquisiti
on time
Year
and
month
The SD memory card lifetime information acquisition time is stored as three-
word BCD data.
e.g. When the acquisition time is 15 hours 55 minutes and 30 seconds on
October 3, 2014, it is stored as follows.
[D2] H1410
[D2+1] H0315
[D2+2] H5530
[D2+1]
Day and
hour
[D2+2]
Minute
and
second

Number of rewrite
information
The ratio (%) of the average number of rewrites of management blocks to
the maximum number of possible rewrites is expressed by the following
formula:
[Number of rewrites (average of all management blocks)] / [Maximum
number of possible rewrites] x 100
(Note 1) The most significant bit of the execution result code can be used as a flag during execution.
