6.14.3.2.7 RX Wait Time Register (0x08)
The RX-wait-time timer is controlled by the value in the RX wait time register 0x08. This timer defines the
time after the end of the transmit operation in which the receive decoders are not active (held in reset
state). This prevents incorrect detections resulting from transients following the transmit operation. The
value of the RX wait time register defines this time in increments of 9.44 μs. This register is preset at
every write to ISO Control register 0x01 according to the minimum tag response time defined by each
standard.
Table 6-35. RX Wait Time Register (0x08)
Function: Defines the time after TX EOF when the RX input is disregarded for example, to block out electromagnetic disturbance
generated by the responding card.
Default: 0x1F at POR = H or EN = L and at each write to ISO control register.

RX wait time
Description
Defines the time after the TX EOF during which the RX input is ignored. Time
starts from the end of TX EOF.
RX wait range is 9.44 μs to 2407 μs (1 to 255), Step size 9.44 μs.
The following default timings are preset by the ISO Control register (0x01):
9.44 μs → FeliCa
66 μs → ISO14443A and B
180 μs → Reserved
B1
Rxw0
293 μs → ISO15693 (TI Tag-It HF-I)
