2.2.19.3 ISO14443 Type B Rx frame COM settings: bits 3-5 (default 00h)
The bits 3 - 5 of this register define the communication settings of ISO 14443 B cards for the
receiving frame.

Description
NoRxSOF
If set to 1 a missing SOF of the received data frame will be ignored.
NoRxEGT
If set to 1 a too short or too long EGT of the received frame will be ignored.
NoRxEOF
If set to 1 a missing EOF of the received data frame will be ignored.
2.2.19.4 ReqA Extended ID: bit 6 (default 0)
If set the Extended ID information for ISO14443 A tags replaces the cascade level information (1
byte) with Request A answer (2 bytes).

2.2.19.5 SAK Extended ID: bit 7 (default 0)
If set the Extended ID information for ISO 14443 A tags will include the SAK byte behind the serial
number.

2.2.20 Modulation Conductance 0 (1Dh)
Default value is 05h.
The modulation defines the conductance of the output driver for the ISO 14443 B and SR176 tags
modulation time. If modulation is set to 10%, also include ISO15693 tags. Use this to regulate the
modulation index. Note that the conductance values are not linear! For further information, refer
to the NXP documentation. [6]

2.2.21 Threshold (1Eh)
Default value is EBh
The higher nibble of the Threshold register defines the minimum accepted signal strength at the
decoder input. The lower nibble of the Threshold register defines the collision level. For further
information, refer to the NXP documentation. [6]
