Hello, we made custom reader board with CR95HF. This reader is interfaces with IMX6 CPU running linux. Communication with reader via SPI bus.

I tried to read DOC9303 biometric passport. I can read it on default speed 106 kbit/sec without problem, now i'm trying to set double speed 212 kbit/sec i have problems with communication after ISO14443A-4 activation. There is no any answer after PPS responce.

Looks like the problem with some of wait time constant or similar other setting for Analog registers.

Is there any hints or set of such constants for different data baud rates?
