DESACTIVATE EAS
Command Code = 0xA1
When receiving the De-activate EAS Request, the
LRI512 reset the non-volatile EAS bit. The
Option_Flag is not supported.
During the write cycle tW, no modulation (never
100% nor 10%) shall occur. If so, the LRI512 may
not reset correctly the EAS bit. The tW delay is a
multiple of t1nominal.
Request parameter (Table 49):
– UID (Optional)
Response parameter (Table 50):
– No parameter.
Response parameter (Table 51):
– Error Code as Error_Flag is set
