Description
FDP CONF
2
11h
FDP CONF defines the configuration of the Field detect pin
00b ... no field detect
01b... enabled by first State-of-Frame (start of communication)
10b... enabled by selection of the tag
11b... enabled by field presence
MIRROR_PAGE
8
00h
MIRROR_Page defines the page for the beginning of the ASCII mirroring
A value in the following range enables the ASCII mirror feature
04h-24h ... valid MIRROR_PAGE values for NTAG213F (UID ASCII mirror)
04h-26h ... valid MIRROR_PAGE values for NTAG 213F (NFC counter mirror only)
04h-22h ... valid MIRROR_PAGE values for NTAG213F (both UID and NFC counter
mirror)
04h-DEh ... valid MIRROR_PAGE values for NTAG216F (UID ASCII mirror)
04h-E0h ... valid MIRROR_PAGE values for NTAG 216F (NFC counter mirror only)
04h-DCh ... valid MIRROR_PAGE values for NTAG216F (both UID and NFC
counter mirror
AUTH0
8
FFh
AUTH0 defines the page address from which the password verification is required.
Valid address range for byte AUTH0 is from 00h to FFh.
If AUTH0 is set to a page address which is higher than the last page from the user
configuration, the password protection is effectively disabled.

0b
0b
One bit inside the ACCESS byte defining the memory protection
0b ... write access is protected by the password verification
1b ... read and write access is protected by the password verification
Write locking bit for the user configuration excluding the PWD and PACK
0b ... user configuration open to write access
CFGLCK
1b ... user configuration permanently locked against write access
Enables the NFC counter
NFC_CNT_EN
0b
0b ... disabled
1b ... enabled
NFC_CNT_PWD
_PROT_EN
0b
enables the password protection to read out and mirror the NFC counter
0b ... the protection is disabled
1b ... the protection is enabled
AUTHLIM
000b
Limitation of negative password verification attempts
000b ... limiting of negative password verification attempts disabled
001b-111b ... maximum number of negative password verification attempts
PWD
PACK
RFUI
32 FFFFFFFFh 32-bit password used for memory access protection
16
-
0000h
all 0b
16-bit password acknowledge used during the password verification process
Reserved for future use - implemented. Write all bits and bytes denoted as RFUI as
0b.
Remark: The CFGLCK bit activates the permanent write protection of the first two
configuration pages. The write lock is only activated after a power cycle of NTAG21xF. If
write protection is enabled, each write attempt leads to a NAK response.
Remark: Most of the user configuration elements get activated only after the RF reset.
