Description
If set, the I/O pins are supporting a fast switching mode.The fast mode
for the I/O’s will increase the peak current consumption of the device,
especially if multiple I/Os are switching at the same time. The power
supply needs to be designed to deliver this peak currents.
-
0h, 1h - The pin SIGOUT is 3-state
2h - The pin SIGOUT is 0
3h - The pin SIGOUT is 1
4h - The pin SIGOUT shows the TX-envelope
5h - The pin SIGOUT shows the TX-active signal
6h - The pin SIGOUT shows the S3C (generic) signal
7h - The pin SIGOUT shows the RX-envelope
(only valid for ISO/IEC 14443A, 106 kBd)
8h - The pin SIGOUT shows the RX-active signal
9h - The pin SIGOUT shows the RX-bit signal
