PROM erasure normal completion: XnD
This signal indicates the normal completion of erasing the parameters in the
E
2
PROM in response to the E
2
PROM erasure request (YnD).
(a) When the E
2
PROM erasure request (YnD) turns on, the parameters in the
E
2
PROM are erased.
(b) On normal completion of erasure, the E
2
PROM erasure normal completion
(XnD) turns on.
(c) By turning off the E
2
PROM erasure request (YnD), the E
2
PROM erasure
normal completion (XnD) turns off.

PROM erasure abnormal completion: XnE
This signal indicates the abnormal completion of erasing the parameters in the
E
2
PROM in response to the E
2
PROM erasure request (YnD).
(a) When the E
2
PROM erasure request (YnD) turns on, the parameters in the
E
2
PROM are erased.
(b) On abnormal completion of erasure, the E
2
PROM erasure abnormal
completion (XnE) turns on and the error code is stored into the E
2
PROM
erasure result (SW00BA) of the buffer memory.
(c) By turning off the E
2
PROM erasure request (YnD), the E
2
PROM erasure
abnormal completion (XnE) turns off.
