2 (0x02): Write User Flash Area

The CFA633 reserves 16 bytes of nonvolatile memory for arbitrary use by the host. This memory can be used to store

a serial number, IP address, gateway address, netmask, or any other data required. All 16 bytes must be supplied.

type: 0x02 = 210

valid data_length is 16

data[] = 16 bytes of arbitrary user data to be stored in

the CFA633's non-volatile memory
