A300 Error Log Pointer When an error occurs, the Error Log
Pointer is incremented by 1 to indicate
the location where the next error record
will be recorded as an offset from the
beginning of the Error Log Area (A100
to A199).
Note 1 The data will be unstable if the
capacitor becomes
discharged.
2 The Error Log Pointer can be
cleared to 00 by turning
A500.14 (the Error Log Reset
Bit) ON.
3 When the Error Log Pointer
has reached 14 hex (20 deci-
mal), the next record is stored
in A195 to A199 when the next
error occurs.
00 to 14 hex Retained Retained Refreshed
when error
occurs.

A310 Manufacturing Lot
Number, Lower Digits
The manufacturing lot number is stored
in 6 digits hexadecimal. X, Y, and Z in
the lot number are converted to 10, 11,
and 12, respectively.
Examples:
Lot number 01805
A310 = 0801, A311 = 0005
Lot number 30Y05
A310 =1130, A311 = 0005
