King Kévin	1200a5228f	sniffer: add waiting time WT update the waiting time (WT) is used to detect timeouts (e.g. for unresponsive card or just to signal an error/NAK). it is essential to detect to timeout to end current data transfer (e.g. change state). by default (after a reset) to timeout is 9600 ETU, but this can change at two places: - after the ATR using the value of TC2 (if present) - after a PPS (only F is used, and not D) because the timeout value can be larger than the 16-bit of the USART TO register, an external variable needs to be used for the count down.

sniffer: add waiting time WT update

the waiting time (WT) is used to detect timeouts (e.g. for
unresponsive card or just to signal an error/NAK). it is essential
to detect to timeout to end current data transfer (e.g. change state).
by default (after a reset) to timeout is 9600 ETU, but this can change
at two places:
- after the ATR using the value of TC2 (if present)
- after a PPS (only F is used, and not D)

because the timeout value can be larger than the 16-bit of the USART
TO register, an external variable needs to be used for the count down.
