1. General description
The NTAG213F and NTAG216F are the new NFC forum compliant Type 2 Tag products
developed by NXP Semiconductors for applications in electronics (i.e. connection
handover, Bluetooth simple pairing, Wi-Fi Protected set-up, device authentication, gaming
and others) - see Figure 1.
On top of offering a large range of User memory (144 bytes for NTAG213F and 888 bytes
for NTAG216F), the NTAG21xF product family offers innovative functionalities like
configuration of the field detection, the SLEEP mode, the FAST_READ command and a
configurable password protection.
The NTAG21xF product family is designed to fully comply to NFC Forum Type 2 Tag
(Ref. 2) and ISO/IEC14443 Type A (Ref. 1) specifications.
The NTAG21xF product family also offers the same package (HXSON4), the same input
capacitance and a full pinning compatibility to the NTAG203F product.
1.1 Contactless energy and data transfer
Communication to NTAG21xF can be established only when the IC is connected to an
antenna. Form and specification of the antenna is out of scope of this document.
When NTAG21xF is positioned in the RF field, the high speed RF communication
interface allows the transmission of the data with a baud rate of 106 kbit/s.

1.2 Simple deployment and user convenience
NTAG21xF offers specific features designed to improve integration and user convenience:
• The fast read capability allows to scan the complete NDEF message with only one
FAST_READ command, thus reducing the communication time overhead
• The improved RF performance allows for more flexibility in the choice of shape,
dimension and materials
• The HXSON4 package delivery form is the same one used as the NTAG203F with the
same pinning
• The field detect functionality is based on an open-drain implementation that requires
only one pull up resistor
1.3 Security
• Manufacturer programmed 7-byte UID for each device
• Capability container with one time programmable bits
• Field programmable read-only locking function per page up to 0Fh page (per 2 pages
(NTAG 213F) or per 16 pages (NTAG 216F) for the extended memory section)
• ECC based originality signature
• 32-bit password protection to prevent unauthorized memory operations
1.4 Field detection
The NTAG21xF product family features an RF field detection functionality based on Open
Drain (see Figure 2) that can be configured with different RF signal or actions trigger:
• upon any RF field presence
• upon the first Start-of-Frame (start of the communication)
• upon the selection of the tag
The corresponding output signal can be used as interrupt source to e.g. wake up an
embedded microcontroller or trigger further actions - e.g. Bluetooth and WiFi pairing. For
more information on this feature, please refer to Ref. 8.

1.5 Sleep mode
The NTAG21xF product family offers the SLEEP mode feature which allows the electronic
device connected with the NTAG21xF to disable the NTAG21xF product by shorting the
field detect pin to ground followed by RF field reset. This enables the electronic device to
hide the NTAG21xF product from the NFC reader device in case e.g. its battery level is
too low or for privacy reason.
1.6 NFC Forum Tag 2 Type compliance
NTAG21xF IC provides full compliance to the NFC Forum Tag 2 Type technical
specification (see Ref. 2) and enables NDEF data structure configurations (see Ref. 3).
1.7 Anticollision
An intelligent anticollision function allows to operate more than one tag in the field
simultaneously. The anticollision algorithm selects each tag individually and ensures that
the execution of a transaction with a selected tag is performed correctly without
interference from another tag in the field.

8.2 RF interface
The RF-interface is based on the ISO/IEC 14443 Type A standard.
During operation, the NFC device generates an RF field. The RF field must always be
present (with short pauses for data communication) as it is used for both communication
and as power supply for the tag.
For both directions of data communication, there is one start bit at the beginning of each
frame. Each byte is transmitted with an odd parity bit at the end. The LSB of the byte with
the lowest address of the selected block is transmitted first. The maximum length of a
NFC device to tag frame is 163 bits (16 data bytes + 2 CRC bytes = 16×9 + 2×9 + 1 start
bit). The maximum length of a fixed size tag to NFC device frame is 307 bits (32 data
bytes + 2 CRC bytes = 32 9 + 2  9 + 1 start bit). The FAST_READ command has a
variable frame length depending on the start and end address parameters. The maximum
frame length supported by the NFC device needs to be taken into account when issuing
this command.
For a multi-byte parameter, the least significant byte is always transmitted first. As an
example, when reading from the memory using the READ command, byte 0 from the
addressed block is transmitted first, followed by bytes 1 to byte 3 out of this block. The
same sequence continues for the next block and all subsequent blocks.
8.3 Data integrity
Following mechanisms are implemented in the contactless communication link between
NFC device and the NTAG21xF to ensure reliable data transmission:

8.4 Communication principle
The commands are initiated by the NFC device and controlled by the Digital Control Unit
of the NTAG21xF. The command response is depending on the communication state of
the IC and for memory operations also on the access limitations valid for the
corresponding page.

8.4.1 IDLE state
After a power-on reset (POR), NTAG21xF switches to the IDLE state. It only exits this
state when a REQA or a WUPA command is received from the NFC device. Any other
data received while in this state is interpreted as an error and NTAG21xF remains in the
IDLE state.
After a correctly executed HLTA command i.e. out of the ACTIVE or AUTHENTICATED
state, the default waiting state changes from the IDLE state to the HALT state. This state
can then be exited with a WUPA command only.
8.4.2 READY1 state
In this state, the NFC device resolves the first part of the UID (3 bytes) using the
ANTICOLLISION or SELECT commands in cascade level 1. This state is correctly exited
after execution of either of the following commands:
• SELECT command from cascade level 1: the NFC device switches NTAG21xF into
READY2 state where the second part of the UID is resolved.
• READ command (from address 0): all anticollision mechanisms are bypassed and the
NTAG21xF switches directly to the ACTIVE state.
Remark: If more than one NTAG is in the NFC device field, a READ command from
address 0 selects all NTAG21xF devices. In this case, a collision occurs due to different
serial numbers. Any other data received in the READY1 state is interpreted as an error
and depending on its previous state NTAG21xF returns to the IDLE or HALT state.
8.4.3 READY2 state
In this state, NTAG21xF supports the NFC device in resolving the second part of its UID
(4 bytes) with the cascade level 2 ANTICOLLISION command. This state is usually exited
using the cascade level 2 SELECT command.
Alternatively, READY2 state can be skipped using a READ command (from address 0) as
described for the READY1 state.
Remark: The response of NTAG21xF to the cascade level 2 SELECT command is the
Select AcKnowledge (SAK) byte. In accordance with ISO/IEC 14443, this byte indicates if
the anticollision cascade procedure has finished. NTAG21xF is now uniquely selected and
only this device will communicate with the NFC device even when other contactless
devices are present in the NFC device field. If more than one NTAG21xF is in the NFC
device field, a READ command from address 0 selects all NTAG21xF devices. In this
case, a collision occurs due to the different serial numbers. Any other data received when
the device is in this state is interpreted as an error. Depending on its previous state the
NTAG21xF returns to either the IDLE state or HALT state.

8.4.4 ACTIVE state
All memory operations and other functions like the originality check are operated in the
ACTIVE state.
The ACTIVE state is exited with the HLTA command and upon reception NTAG21xF
transits to the HALT state. Any other data received when the device is in this state is
interpreted as an error. Depending on its previous state NTAG21xF returns to either the
IDLE state or HALT state.
NTAG21xF transits to the AUTHENTICATED state after successful password verification
using the PWD_AUTH command.
8.4.5 AUTHENTICATED state
In this state, all memory operations as well as all operations on memory pages, which are
configured as password verification protected, can be accessed.
The AUTHENTICATED state is exited with the HLTA command and upon reception
NTAG21xF transits to the HALT state. Any other data received when the device is in this
state is interpreted as an error. Depending on its previous state NTAG21xF returns to
either the IDLE state or HALT state.
8.4.6 HALT state
HALT and IDLE states constitute the two wait states implemented in NTAG21xF. An
already processed NTAG21xF can be set into the HALT state using the HLTA command.
In the anticollision phase, this state helps the NFC device to distinguish between
processed tags and tags yet to be selected. NTAG21xF can only exit this state on
execution of the WUPA command. Any other data received when the device is in this state
is interpreted as an error and NTAG21xF state remains unchanged.

8.5.1 UID/serial number
The unique 7-byte serial number (UID) and its two check bytes are programmed into the
first 9 bytes of memory covering page addresses 00h, 01h and the first byte of page 02h.
The second byte of page address 02h is reserved for internal data. These bytes are
programmed and write protected in the production test.

In accordance with ISO/IEC 14443-3 check byte 0 (BCC0) is defined as CT Å SN0 Å SN1
Å SN2 and check byte 1 (BCC1) is defined as SN3 Å SN4 Å SN5 Å SN6.
SN0 holds the Manufacturer ID for NXP Semiconductors (04h) in accordance with
ISO/IEC 14443-3.
8.5.2 Static lock bytes (NTAG21xF)
The bits of byte 2 and byte 3 of page 02h represent the field programmable read-only
locking mechanism. Each page from 03h (CC) to 0Fh can be individually locked by setting
the corresponding locking bit Lx to logic 1 to prevent further write access. After locking,
the corresponding page becomes read-only memory.
The three least significant bits of lock byte 0 are the block-locking bits. Bit 2 deals with
pages 0Ah to 0Fh, bit 1 deals with pages 04h to 09h and bit 0 deals with page 03h (CC).
Once the block-locking bits are set, the locking configuration for the corresponding
memory area is frozen.

COMPATIBILITY_WRITE command, and the contents of the lock bytes are bit-wise
OR’ed and the result then becomes the new content of the lock bytes. This process is
irreversible. If a bit is set to logic 1, it cannot be changed back to logic 0.
The contents of bytes 0 and 1 of page 02h are unaffected by the corresponding data bytes
of the WRITE or COMPATIBILITY_WRITE command.
The default value of the static lock bytes is 00 00h.
Any write operation to the static lock bytes is tearing-proof.
8.5.3 Dynamic Lock Bytes (NTAG21xF)
To lock the User Memory pages of NTAG21xF starting at page address 10h and onwards,
the so called dynamic lock bytes are used. The dynamic lock bytes are located at page
28h for NTAG213F and at page E2h for NTAG216F. The three lock bytes cover the
memory area of 96 data bytes for NTAG213F and 830 data bytes for NTAG216F. The
granularity is 2 pages for NTAG213F and 16 pages for NTAG216F compared to a single
page for the first 48 bytes as shown in Figure 10 and Figure 11.
Remark: It is recommended to set all bits marked with RFUI to 0, when writing to the
dynamic lock bytes.
Remark: For the correct usage of the dynamic lock bytes with NFC devices for the
NTAG216F refer to Ref. 9 “AN11456 NTAG21x Using the dynamic lock bits to lock the
tag”.

8.5.4 Capability Container (CC bytes)
The Capability Container CC (page 3) is programmed during the IC production according
to the NFC Forum Type 2 Tag specification (see Ref. 2). These bytes may be bit-wise
modified by a WRITE or COMPATIBILITY_WRITE command. See example for
NTAG213F in Figure 12.

Fig 12. CC bytes
The parameter bytes of the WRITE command and the current contents of the CC bytes
are bit-wise OR’ed. The result is the new CC byte contents. This process is irreversible
and once a bit is set to logic 1, it cannot be changed back to logic 0.
Any write operation to the CC bytes is tearing-proof.
Byte 2 in the capability container defines the available memory size for NDEF messages.
The configuration at delivery is shown in Table 4.

The default values of the CC bytes at delivery are defined in Section 8.5.6.
To maintain compatibility to NFC Forum Type 2 tTag specification (and interoperability with
different NFC device), it is recommended to not change the default capability container
content.
8.5.5 Data pages
Pages 04h to 27h for NTAG213F and 04h to E1h for NTAG216F are the user memory

8.6 NFC counter function
NTAG21xF features a NFC counter function. This function enables NTAG21xF to
automatically increase the 24 bit counter value, triggered by the first
• READ command or
• FAST-READ command
after the NTAG21xF tag is powered by an RF field.
The NFC counter is enabled or disabled with the NFC_CNT_EN bit (see Section 8.5.7).
The actual NFC counter value can be read with
• READ_CNT command or
• NFC counter mirror feature
The reading of the NFC counter (by both above listed ways or with the NFC counter
mirror) can also be protected with the password authentication. The NFC counter
password protection is enabled or disabled with the NFC_CNT_PWD_PROT bit (see
Section 8.5.7).
8.7 ASCII mirror function
NTAG21xF features a ASCII mirror function. This function enables NTAG21xF to virtually
mirror
• 7 byte UID (see Section 8.7.1) or
• 3 byte NFC counter value (see Section 8.7.2) or
• both, 7 byte UID and 3 byte NFC counter value with a separation byte (see
Section 8.7.3)
into the physical memory of the IC in ASCII code. On the READ or FAST READ command
to the involved user memory pages, NTAG21xF will respond with the virtual memory
content of the UID and/or NFC counter value in ASCII code.
The required length of the reserved physical memory for the mirror functions is specified
in Table 11.

The position within the user memory where the mirroring of the UID and/or NFC counter
shall start is defined by the MIRROR_PAGE and MIRROR_BYTE values.
The MIRROR_PAGE value defines the page where the ASCII mirror shall start and the
MIRROR_BYTE value defines the starting byte within the defined page.
The ASCII mirror function is enabled with a MIRROR_PAGE value specified in the range
of Table 10.

NFC Forum T2T IC with 144/888 bytes user memory and field detection
The MIRROR_CONF bits (see Table 9 and Table 11) define if ASCII mirror shall be
enabled for the UID and/or NFC counter.
If both, the UID and NFC counter, are enabled for the ASCII mirror, the UID and the NFC
counter bytes are separated automatically with an “x” character (78h ASCII code).
8.7.1 UID ASCII mirror function
This function enables NTAG21xF to virtually mirror the 7 byte UID in ASCII code into the
physical memory of the IC. The length of the UID ASCII mirror requires 14 bytes to mirror
the UID in ASCII code. On the READ or FAST READ command to the involved user
memory pages, NTAG21xF will respond with the virtual memory content of the UID in
ASCII code.
The position within the user memory where the mirroring of the UID shall start is defined
by the MIRROR_PAGE and MIRROR_BYTE values.
The MIRROR_PAGE value defines the page where the UID ASCII mirror shall start and
the MIRROR_BYTE value defines the starting byte within the defined page.
The UID ASCII mirror function is enabled with a MIRROR_PAGE value >03h and the
MIRROR_CONF bits are set to 01b.
Remark: Please note that the 14 bytes of the UID ASCII mirror shall not exceed the
boundary of the user memory, otherwise the mirroring is not executed.

8.7.2 NFC counter mirror function
This function enables NTAG21xF to virtually mirror the 3 byte NFC counter value in ASCII
code into the physical memory of the IC. The length of the NFC counter mirror requires 6
bytes to mirror the NFC counter value in ASCII code. On the READ or FAST READ
command to the involved user memory pages, NTAG21xF will respond with the virtual
memory content of the NFC counter in ASCII code.
The position within the user memory where the mirroring of the NFC counter shall start is
defined by the MIRROR_PAGE and MIRROR_BYTE values.
The MIRROR_PAGE value defines the page where the NFC counter mirror shall start and
the MIRROR_BYTE value defines the starting byte within the defined page.
The NFC counter mirror function is enabled with a MIRROR_PAGE and MIRROR_BYTE
value according to Table 10 and the MIRROR_CONF bits are set to 10b.
If the NFC counter is password protected with the NFC_CNT_PWD_PROT bit set to 1b
(see Section 8.5.7), the NFC counter will only be mirrored into the physical memory, if a
valid password authentication has been executed before.

8.7.3 UID and NFC counter mirror function
This function enables NTAG21xF to virtually mirror the 7 byte UID and 3byte NFC counter
value in ASCII code into the physical memory of the IC separated by 1 byte (“x” character,
78h). The length of the mirror requires 21 bytes to mirror the UID, NFC counter value and
the separation byte in ASCII code. On the READ or FAST READ command to the involved
user memory pages, NTAG21xF will respond with the virtual memory content of the UID
and NFC counter in ASCII code.
The position within the user memory where the mirroring shall start is defined by the
MIRROR_PAGE and MIRROR_BYTE values.
The MIRROR_PAGE value defines the page where the mirror shall start and the
MIRROR_BYTE value defines the starting byte within the defined page.
The UID and NFC counter mirror function is enabled with a MIRROR_PAGE and a
MIRROR_BYTE value according to Table 10 and the MIRROR_CONF bits are set to 11b.
If the NFC counter is password protected with the NFC_CNT_PWD_PROT bit set to 1b
(see Section 8.5.7), the NFC counter will only be mirrored into the physical memory, if a
valid password authentication has been executed before.

8.8 Sleep mode
If the sleep mode is enabled (see configuration bit Table 10) and the electronic device
(e.g. a microcontroller) connected to the NTAG21xF device brings the Field detection pin
to GROUND and the NFC device triggers RF reset, then the NTAG21xF device will enter
into the sleep mode where it will become invisible for the NFC device (e.g. phone).
This mode is only effective after RF reset, i.e. even if the Field detect pin is brought to
ground during HF communication, this will have no impact on the ongoing device
activities.
See Ref. 8 for additional information and Table 42 for the voltage range to be applied on
the field detection pin for effective sleep mode.
The Field detect pin shall not be left floating.

8.9 Password verification protection
The memory write or read/write access to a configurable part of the memory can be
constrained to a positive password verification. The 32-bit secret password (PWD) and
the 16-bit password acknowledge (PACK) response shall be typically programmed into
the configuration pages at the tag personalization stage.
The AUTHLIM parameter specified in Section 8.5.7 can be used to limit the negative
verification attempts.
In the initial state of NTAG21xF, password protection is disabled by a AUTH0 value of
FFh. PWD and PACK are freely writable in this state. Access to the configuration pages
and any part of the user memory can be restricted by setting AUTH0 to a page address
within the available memory space. This page address is the first one protected.
Remark: The password protection method provided in NTAG21xF has to be intended as
an easy and convenient way to prevent unauthorized memory accesses. If a higher level
of protection is required, cryptographic methods can be implemented at application layer
to increase overall system security.
8.9.1 Programming of PWD and PACK
The 32-bit PWD and the 16-bit PACK need to be programmed into the configuration
pages, see Section 8.5.7. The password as well as the password acknowledge are written
LSByte first. This byte order is the same as the byte order used during the PWD_AUTH
command and its response.
The PWD and PACK bytes can never be read out of the memory. Instead of transmitting
the real value on any valid READ or FAST_READ command, only 00h bytes are replied.
If the password verification does not protect the configuration pages, PWD and PACK can
be written with normal WRITE and COMPATIBILITY_WRITE commands.
If the configuration pages are protected by the password configuration, PWD and PACK
can be written after a successful PWD_AUTH command.
The PWD and PACK are writable even if the CFGLCK bit is set to 1b. Therefore it is
strongly recommended to set AUTH0 to the page where the PWD is located after the
password has been written. This page is 2Bh for NTAG213F and E5h for NTAG216F.
Remark: To improve the overall system security, it is advisable to diversify the password
and the password acknowledge using a die individual parameter of the IC, which is the
7-byte UID available on NTAG21xF.

8.9.2 Limiting negative verification attempts
To prevent brute-force attacks on the password, the maximum allowed number of
negative password verification attempts can be set using AUTHLIM. This mechanism is
disabled by setting AUTHLIM to a value of 000b, which is also the initial state of
NTAG21xF.
If AUTHLIM is not equal to 000b, each negative authentication verification is internally
counted. As soon as this internal counter reaches the number specified in AUTHLIM, any
further negative password verification leads to a permanent locking of the protected part
of the memory for the specified access modes. Independently, whether the provided
password is correct or not, each subsequent PWD_AUTH fails.
Any successful password verification, before reaching the limit of negative password
verification attempts, resets the internal counter to zero.
8.9.3 Protection of special memory segments
The configuration pages can be protected by the password authentication as well. The
protection level is defined with the PROT bit.
The protection is enabled by setting the AUTH0 byte to a value that is within the
addressable memory space and that is at least the first page address of the configuration
pages (29h for NTAG 213F or E3h for NTAG 216F).
8.10 Originality signature
NTAG21xF features a cryptographically supported originality check. With this feature, it is
possible to verify with a certain confidence that the tag is using an IC manufactured by
NXP Semiconductors. This check can be performed on personalized tags as well.
NTAG21xF digital signature is based on standard Elliptic Curve Cryptography, according
to the ECDSA algorithm. The use of a standard algorithm and curve ensures easy
software integration of the originality check procedure in an application running on a NFC
devices without specific hardware requirements.
Each NTAG21xF UID is signed with a NXP private key and the resulting 32-byte signature
is stored in a hidden part of the NTAG21xF memory during IC production.
This signature can be retrieved using the READ_SIG command and can be verified in the
NFC device by using the corresponding ECC public key provided by NXP. In case the
NXP public key is stored in the NFC device, the complete signature verification procedure
can be performed offline.
To verify the signature (for example with the use of the public domain crypto library
OpenSSL) the tool domain parameters shall be set to secp128r1, defined within the
standards for elliptic curve cryptography SEC (Ref. 7).
Details on how to check the signature value are provided in following application note
(Ref. 5). It is foreseen to offer not only offline, as well as online way to verify originality of
NTAG21xF.

This command is new in NTAG21xF compared to NTAG203F.
9.2 Timings
The command and response timings shown in this document are not to scale and values
are rounded to 1 s.
All given command and response times refer to the data frames including start of
communication and end of communication. They do not include the encoding (like the
Miller pulses). A NFC device data frame contains the start of communication (1 “start bit”)
and the end of communication (one logic 0 + 1 bit length of unmodulated carrier). A NFC
tag data frame contains the start of communication (1 “start bit”) and the end of
communication (1 bit length of no subcarrier).
The minimum command response time is specified according to Ref. 1 as an integer n
which specifies the NFC device to NFC tag frame delay time. The frame delay time from
NFC tag to NFC device is at least n=9 (approximately 87s). The maximum command
response time is specified as a time-out value. Depending on the command, the TACK
value specified for command responses defines the NFC device to NFC tag frame delay

The most significant 7 bits of the storage size byte are interpreted as a unsigned integer
value n. As a result, it codes the total available user memory size as 2n. If the least
significant bit is 0b, the user memory size is exactly 2n. If the least significant bit is 1b, the
user memory size is between 2n and 2n+1.
The user memory for NTAG213F is 144 bytes. This memory size is between 128 bytes
(27) and 256 bytes (28). Therefore, the most significant 7 bits of the value 0Fh are
interpreted as 7d and the least significant bit is 1b.
The user memory for NTAG216F is 888 bytes. This memory size is between 512 bytes
(29) and 1024 bytes (210). Therefore, the most significant 7 bits of the value 13h are
interpreted as 9d and the least significant bit is 1b.

10.2 READ
The READ command requires a start page address, and returns the 16 bytes of four
NTAG21xF pages. For example, if address (Addr) is 03h then pages 03h, 04h, 05h, 06h
are returned. Special conditions apply if the READ command address is near the end of
the accessible memory area. The special conditions also apply if at least part of the
addressed pages is within a password protected area. For details on those special
condition see the end of the paragraph and the roll over mechanism.
The command structure is shown in Figure 15 and Table 28.

A roll-over mechanism is implemented to continue reading from page 00h once the end of
the accessible memory is reached. Reading from address 2Ah on a NTAG213F results in
pages 2Ah, 2Bh, 2Ch and 00h being returned.
The following conditions apply if part of the memory is password protected for read
access:
• if NTAG21xF is in the ACTIVE state
– addressing a page which is equal or higher than AUTH0 results in a NAK response
– addressing a page lower than AUTH0 results in data being returned with the
roll-over mechanism occurring just before the AUTH0 defined page
• if NTAG21xF is in the AUTHENTICATED state
– the READ command behaves like on a NTAG21xF without access protection
Remark: PWD and PACK values can never be read out of the memory. When reading
from the pages holding those two values, all 00h bytes are replied to the NFC device
instead.

10.3 FAST_READ
The FAST_READ command requires a start page address and an end page address and
returns the all n*4 bytes of the addressed pages. For example if the start address is 03h
and the end address is 07h then pages 03h, 04h, 05h, 06h and 07h are returned. If the
addressed page is outside of accessible area, NTAG21xF replies a NAK.

10.5 COMPATIBILITY_WRITE
The COMPATIBILITY_WRITE command is implemented to guarantee interoperability with
the established MIFARE Classic PCD infrastructure, in case of coexistence of ticketing
and NFC applications. Even though 16 bytes are transferred to NTAG21xF, only the least
significant 4 bytes (bytes 0 to 3) are written to the specified address. It is recommended to
set all the remaining bytes, 04h to 0Fh, to logic 00h. The COMPATIBILITY_WRITE
command is shown in Figure 18, Figure 19 and Table 32.

10.7 PWD_AUTH
A protected memory area can be accessed only after a successful password verification
using the PWD_AUTH command. The AUTH0 configuration byte defines the protected
area. It specifies the first page that the password mechanism protects. The level of
protection can be configured using the PROT bit either for write protection or read/write
protection. The PWD_AUTH command takes the password as parameter and, if
successful, returns the password authentication acknowledge, PACK. By setting the
AUTHLIM configuration bits to a value larger than 000b, the number of unsuccessful
password verifications can be limited. Each unsuccessful authentication is then counted in
a counter featuring anti-tearing support. After reaching the limit of unsuccessful attempts,
the memory access specified in PROT, is no longer possible. The PWD_AUTH command
is shown in Figure 21 and Table 38.
