Receiver gain adjust
Note: The command code values from Table 5-29 are substituted in Table 5-32, bit 0 through bit 4. Also,
the most-significant bit (MSB) in Table 5-31 must be set to 1.
5.4.2
Reset
The reset command clears the FIFO contents and FIFO status register (1Ch). It also clears the register
storing the collision error location (0Eh).
5.4.3
Transmission With CRC
The transmission command must be sent first, followed by transmission length bytes, and FIFO data. The
reader starts transmitting after the first byte is loaded into the FIFO. The CRC byte is included in the
transmitted sequence.
5.4.4
Transmission Without CRC
Same as Section 5.4.3 with CRC excluded.
5.4.5
Delayed Transmission With CRC
The transmission command must be sent first, followed by the transmission length bytes, and FIFO data.
The reader transmission is triggered by the TX timer.
5.4.6
Delayed Transmission Without CRC
Same as above with CRC excluded.
5.4.7
Transmission Next Slot
When this command is received, the reader transmits the next slot command. The next slot sign is defined
by the protocol selection.
5.4.8
Receiver Gain Adjust
This command should be executed when the MCU determines that no TAG response is coming and when
