3) Host commands received and processed.
When the RWD receives commands from the host computer, the polling rate increases
to allow a quick response to the command. This means that commands such as READ
or WRITE BLOCK can be repeated quickly and the large amounts of data read from,
or written to the card as fast as possible.
The polling cycle delay in this case is effectively the minimum, so the RWD responds
to the host command immediately after the RF communication is complete.
Example a) NO card present, single CARD UID (0x55) command received.
Note: at 9600 baud serial communication rate, a single byte is received or transmitted in
approximately 1mS (104 μ S per bit). If no commands follow then the polling rate reverts
back to the stored parameter value as in (1).

Host waits for CTS falling edge then sends command byte.
RWD processes command, RF turned ON for brief period to check if card present.
RWD then replies with acknowledge byte (+ data).
