8.5 Set NFC timings
Use this command to set various operating timings for the NFC reader. This is an 11-byte command
starting for the command byte.
Warning: Access-IS optimise the NFC timings for the LSR118 and these values should not
need to be changed. The NFC module does not modify a timing value if its value is set to
zero (0) when you send the command. Using this command incorrectly may cause the
device to become inoperable.
