Byte 4 contains the current version number.
9.2.2
Register initialization files (read/write)
Register initialization from address 10h to address 2Fh is performed automatically during
the initializing phase (see
Section 9.7.3 on page 25
) using the StartUp register
initialization file.
In addition, the MFRC500 registers can be initialized using values from the register
initialization file when the LoadConfig command is executed (see
Section 11.4.1 on
page 79
).
Remark:
The following points apply to initialization:
the Page register (addressed using 10h, 18h, 20h, 28h) is skipped and not initialized.
PreSetxx registers: do not change.
all reserved register bits set to logic 0: do not change.
9.2.2.1
StartUp register initialization file (read/write)
The EEPROM memory block address 1 and 2 contents are used to automatically set the
register subaddresses 10h to 2Fh during the initialization phase. The default values stored
in the EEPROM during production are shown in
Section 9.2.2.2 “Factory default StartUp
register initialization file”
