Remark
[1]
In order to support 7 byte UID Mifare class, the firmware of SL025 has been
updated to Ver1.2 in Mar 2011.
And older firmware version (such as Ver1.0, 1. 1) only supports 4 byte UID.
Please refer to NXP Customer Letter UID for detailed information of 4 byte & 7 byte
UID of Mifare products.
[2]
To support NATG203, the firmware of SL025 has been updated to Ver1.6 in May
2012. The older firmware version only supports reading/writing data page address less
tha n 16.
