Acknowledge
An acknowledge must be sent at the end of one data byte. The acknowledge-related clock
pulse is generated by the master. The transmitter of data, either master or slave, releases
the SDA line (HIGH) during the acknowledge clock pulse. The receiver pulls down the
SDA line during the acknowledge clock pulse so that it remains stable LOW during the
HIGH period of this clock pulse.
The master can then generate either a STOP (P) condition to stop the transfer or a
repeated START (Sr) condition to start a new transfer.
A master-receiver indicates the end of data to the slave-transmitter by not generating an
acknowledge on the last byte that was clocked out by the slave. The slave-transmitter
releases the data line to allow the master to generate a STOP (P) or repeated START (Sr)
condition.

Register read access
To read out data from a specific register address in the Module, the host controller must
use the following procedure:
• Firstly, a write access to the specific register address must be performed as indicated
in the frame that follows
• The first byte of a frame indicates the device address according to the I2C-bus rules
• The second byte indicates the register address. No data bytes are added
• The Read/Write bit is 0
After the write access, read access can start. The host sends the device address of the
PN512. In response, the Module sends the content of the read access register. In one
frame all data bytes can be read from the same register address. This enables fast FIFO
buffer access or register polling.
The Read/Write (R/W) bit is set to logic 1.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
‐ Reorient or relocate the receiving antenna.
‐ Increase the separation between the equipment and receiver.
‐ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
‐ Consult the dealer or an experienced radio/TV technician for help.
FCC Caution:
Any changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause undesired
operation.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
transmitter module must not be co‐located or operating in conjunction with any other antenna or
transmitter.
IMPORTANT NOTE:
In the event that these conditions can not be met (for example certain laptop configurations or co‐location
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not
be used on the final product. In these circumstances, the OEM integrator will be responsible for
re‐evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
End Product Labeling:
The final end product must be labeled in a visible area with the following:
【Contains FCC ID: 2AB9W‐NFC001】
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user’s manual of the end product which integrates this module.
